    A one and one-half year old steer killed in a slaughterhouse had necrobacillary fibrinous bronchopneumonia with abscessation. Histologically, there were variably sized areas of coagulation necrosis in the lungs, thrombosis of pulmonary lymphatics, and fibrin deposits in the bronchioli and adjacent alveoli. Fusobacterium necrophorum in pure culture was isolated from the lung.

  2. Determinants of broncho-pneumonia in children

    International Nuclear Information System (INIS)

    Bronchopneumonia is acute inflammation of the bronchioles which is characterized by multiple foci of isolated, acute consolidation that affects one or more pulmonary lobules. Objectives: To find out the determinants of bronchopneumonia in children up to 12 years visiting Mayo hospital from February to July 2013. Design: Population based case control study. Place: Lahore. Study Period: 06 months. Subjects and Methods: Population based case-control study with I:I case to control ratio was conducted. A total of 100 subjects (50 cases and 50 controls) were recruited in study. Selection was made on laid down criteria after taking due consent. Interviews were conducted through a pretested questionnaire. Data was collected, compiled and analyzed through SPSS version 20.After describing the demographic characteristics using frequency tables, simple and multivariate logistic regression were used to calculate odds ratio and their 95% confidence intervals. Results: In multivariate analysis, while controlling all other risk factors, prematurity (OR: 4.720 95% CI: 1.559 - 14.286) and poor access to health care (OR: 2.557 95% CI: 1.049 - 6.231) were found to be significantly associated with bronchopneumonia.

  4. Lymphoma and broncho-pneumonia in a calf

    International Nuclear Information System (INIS)

    A one and a half month old Holstein calf was presented with a chronic respiratory condition. Clinical examination revealed cachexia and lymphadenopathy and wheezes and crepitations on auscultation. Blood cell count indicated a non-regenerative microcytic anaemia and marked lymphopenia. Broncho-pneumonia due to Mycoplasma bovis was diagnosed after radiography and cytobacteriology of transtracheal lavage. A large cell lymphoma was suspected after finding a high proportion of large lymphocytes in a lymph node puncture aspirate. Serology for bovine leukosis was negative. A diagnosis of juvenile lymphoma associated with M. bovis broncho-pneumonia was established. The diagnosis was confirmed on post-mortem. Juvenile lymphoma is rare. Affected animals are aged between two and six months and systematically present generalised lymphadenopathy. This disease is always fatal. When an animal is presented with generalised lymphadenopathy, this condition should be eliminated by lymph node puncture of a moderately hypertrophied lymph node before other tests are performed

    We report a 53-year-old female who presented with complaints of sudden onset breathlessness, cough with expectoration for 6 months, and a right lung base lesion in the chest X-ray, which was diagnosed and treated as bronchopneumonia by the family physician. High-resolution computed tomography of the chest was done which revealed a large heterogeneously enhancing mass in the right thoracic cavity. She underwent thoracotomy and was found to have a giant encapsulated and well-circumscribed mass arising from the pleura. Excision biopsy of the mass revealed it to be an ancient schwannoma. Ancient schwannoma of the pleura is a very rare entity. Complete surgical resection is curative.

    Full Text Available AIM: Poorly treated bronchopneumonia is the most common cause of empyema thoracis in Nigeria. Ignorance poverty and quackery are the major reasons for inadequate treatment. METHOD: All paediatric patients diagnosed and treated for empyema thoracis secondary to poorly treated bronchopneumonia in our hospital between November 2006 and January 2009 had their case notes retrieved, and data collated into individual proforma for analysis. RESULTS: During the 26 months period, there were 2106 admissions into children emergency unit of our hospital, with 267 having bronchopneumonia (12% and 18 having empyema thoracis (6.7% case prevalence. The age range was 1 month to 16 years with mean of 6.4 years and male: female ratio 3.5: 1. The right pleural space was affected in 50%, left pleural space in 33.33%, and both pleural spaces in 16.66%. Up to 61% of mothers of the patients with empyema thoracis had no or only primary level of formal education, 77.78% of such mothers were not gainfully employed and 44.43% of patients were previously treated by medical charlatans before presentation in our hospital. All patients were successfully treated with antibiotic and tube thoracostomy drainage with satisfactory recovery. CONCLUSION: Empyema thoracis 20 poorly treated bronchopneumonia is still prevalent in Nigeria. Mass literacy campaign, poverty alleviation and provision of affordable and easily accessible medical care throughout the whole country are the immediate solution to this menace.

    Six English bulldog and nine nonbrachycephalic puppies with bronchopneumonia and radiographs were evaluated. Relative size of the trachea was measured by the tracheal diameter (TD) and the thoracic inlet distance (TI), expressed as a ratio (TD:TI). At diagnosis of bronchopneumonia, there was a significant difference between the median TD:TI of the bulldog puppies (0.07; range, 0.06-0.09) and that of the nonbrachycephalic puppies (0.14; range, 0.11-0.25; P=0.0004). At the same time, there was also a significant difference between the mean TD:TI of bulldog puppies (0.07±0.01) and that of nonbrachycephalic puppies (0.15±0.05; P=0.002). Follow-up radiographs showed significant increases in TD:TI ratio in all six bulldogs (median TD:TI = 0.14; range, 0.12-0.18; P=0.03 and mean TD:TI = 0.15±0.02; P=0.0007), whereas the ratio did not change significantly in the nonbrachycephalic control group (median TD:TI = 0.17; range, 0.14-0.22; P=0.10 and mean TD:TI = 0.18±0.03; P=0.06). Tracheal hypoplasia in some brachycephalic dogs might partially or completely resolve with growth to mature body size. PMID:21852513

    Broiler chickens on several farms from a single poultry company experienced neurological signs and mortality in chicks between 3 days and 10 days of age over a 3-week period after use of a fowlpox-vectored infectious laryngotracheitis virus vaccine in ovo. At necropsy the lungs contained numerous tan or gray, opaque to translucent, 0.5- to 2.0-mm nodules in the parenchyma. Microscopic lesions were a multifocal severe lymphohistiocytic and heterophilic bronchopneumonia. Immunohistochemistry was positive for fowlpox virus in macrophages and lymphocytes, and polymerase chain reaction on paraffin-embedded lung tissues was positive for a fowlpox vector virus commonly used as a vaccine. The cause of the neurological signs was not determined. PMID:20080499

    Full Text Available Pneumonia in preruminant calves is a multifactorial disease. Infectious agents, the environment, management and the immune status of the calves are all important factors in determining the outcome of an infection. Until today, the level and composition of circulating immune complexes in preruminant calves with pneumonia have not been studied in detail. We performed this work with the aim to determine whether pneumonia in three-month-old calves is followed by changes in the immune complex level and changes in the γ-globulin level as their possible constituents. Immune complexes from the calves’ sera were isolated by polyethylene glycol (PEG precipitation methods. Optical density at 350 nm (OD350 of redissolved precipitates was measured to determine the circulating immune complexes level. The OD350 level of PEG precipitates of calves with pneumonia at the time of diagnosis was 0.577±0.206 and it was statistically significantly higher (p<0.001 than OD350 the level of PEG precipitates of healthy calves (0.286±0.080. Electrophoretic analysis of sera and PEG precipitates showed that both slow and fast γ-globulins are found among serum and immune-complexes' γ-globulins, but the concentration of fast γ-globulins was significantly lower in sera of diseased calves. The level of PEG precipitable immune complexes was not correlated with the concentration of serum and PEG precipitable g-globulins. The results of this study have shown that by relatively simple PEG precipitation assay it is possible to detect an increased level of circulating immune complexes in calves with pneumonia. This can be used as an additional diagnostic parameter for the detection and follow up of the disease.

    Full Text Available Introduction: Pneumonia is the most commondiagnosis made in hospitalised children. The MalaysianClinical Practice Guidelines on pneumonia andrespiratory tract infections provides a comprehensiveguidance in the local context. We evaluated thedocumented assessment and management of childrendiagnosed with pneumonia admitted to the children’sward, Hospital Batu Pahat against this guideline.Methods: We performed a retrospective analysis ofhospital case notes for children admitted from Januaryto May 2004.Results: Ninety six case notes were analysed. Mostpatients (84% had at least four positive clinical featuresleading to the diagnosis of pneumonia. 92% met theguideline criteria for admission. Sp02 was performed for58% on admission, and 58% with reading below 95%received supplemental oxygen. Throughout hospitalstay, each patient had an average of four investigations(range: 1 – 12. Among 23 patients who hadfurther investigations, justifications were only recordedin seven patients (30.4%, and changes inmanagement resulted in 23%. The most commonantibiotic prescribed was intravenous Penicillin (97 %.In 17 patients who met the guideline classification forsevere pneumonia, none received the recommendedantibiotic combination. The median time to feverresolution was 22 hours (range 2 – 268, and medianhospital stay was 3 days (range 1 – 12.Conclusions: Although the quality of clinicalassessment and antibiotic choices were acceptable,there was a failure to critically evaluate patientsaccording to disease severity and initiate correspondinginvestigations and managements. Future efforts need tobe directed at promoting further guideline adherenceand the exercise of critical judgment in patientevaluation.

  19. Lung structure-respiratory function relationships in experimentally-induced bronchiolitis, bronchopneumonia and interstitial pneumonia in rats

    International Nuclear Information System (INIS)

    Histopathology and respiratory function of rats with three different types and distributions of lower lung inflammation were compared to better understand lung structure-function relationships. Rats were exposed 21 h/day for 7 days to 0.8 ppm ozone (O3), sham-exposed as controls, or given 5 mg/kg bacterial endotoxin either intratracheally (ITE) or intraperitoneally (IPE). Respiratory function was measured 24 h after the end of treatment, than the rats were sacrificed and the distribution of inflammation was evaluated morphometrically. Chronic centriacinar inflammation with formation of new respiratory bronchioles caused an obstructive functional impairment in the O3 rats, which was clearly distinguished from the restrictive impairments resulting from acute inflammation in ITE and IPE rats. Only the magnitudes of changes related to the distribution of inflammation differentiated the ITE and IPE groups. Flow parameters previously thought sensitive to large airway resistance were changed in the O3 rats. Alveolar luminal inflammatory exudate affected quasistatic compliance more than septal inflammation in ITE and IPE rats. Quasistatic chord compliance was the most sensitive of three indices of pressure-volume relationships. The findings in this study improve the basis for interpreting respiratory function changes of rats. (author)

    Avian influenza viruses continue to cross the species barrier, and if such viruses become transmissible among humans, it would pose a great threat to public health. Since its emergence in China in 2013, H7N9 has caused considerable morbidity and mortality. In the absence of a universal influenza vaccine, preparedness includes development of subtype-specific vaccines. In this study, we developed and evaluated in ferrets an intranasal live attenuated influenza vaccine (LAIV) against H7N9 based on the A/Leningrad/134/17/57 (H2N2) cold-adapted master donor virus. We demonstrate that the LAIV is attenuated and safe in ferrets and induces high hemagglutination- and neuraminidase-inhibiting and virus-neutralizing titers. The antibodies against hemagglutinin were also cross-reactive with divergent H7 strains. To assess efficacy, we used an intratracheal challenge ferret model in which an acute severe viral pneumonia is induced that closely resembles viral pneumonia observed in severe human cases. A single- and two-dose strategy provided complete protection against severe pneumonia and prevented virus replication. The protective effect of the two-dose strategy appeared better than the single dose only on the microscopic level in the lungs. We observed, however, an increased lymphocytic infiltration after challenge in single-vaccinated animals and hypothesize that this a side effect of the model. PMID:26796670

    To evaluate the frequency of short-term pulmonary complications in the patients undergoing various head and neck cancer surgeries in our setup and to assess possible risk factors responsible for these complications. Seventy patients of age group 20 to 80 years, regardless of gender, treated surgically for head and neck cancers were enrolled. Main outcome measures included development of pulmonary complications following 15 days of oncological surgery. The complications studied were pneumothorax, bronchopneumonia, atelectasis, pulmonary embolism and cardiopulmonary arrest. A total of 24.28% patients suffered from postoperative pulmonary complications; 17.14% developed bronchopneumonia, 5.71% pulmonary embolism, and 1.42% went into cardiopulmonary arrest, none developed pneumothorax or pulmonary atelectasis. A significant correlation of postoperative bronchopneumonia was seen with heavy smoking and assisted ventilation. Pulmonary embolism was associated with extended assisted ventilation and prolonged surgery. Cardiopulmonary arrest was associated with comorbidity and assisted ventilation after surgery. The frequency of bronchopneumonia supersedes all of the postoperative pulmonary complications in head and neck oncological surgery. Patients at risk of developing postoperative complications are heavy smokers, diabetics, those undergoing prolonged surgery, tracheostomy, and extended assisted ventilation. (author)

    This study determined the prevalence of diseases and pathogens associated with mortality or severe morbidity in 72 Ontario beef feedlots in calves that died or were euthanized within 60 days after arrival. Routine pathologic and microbiologic investigations, as well as immunohistochemical staining for detection of bovine viral diarrhea virus (BVDV) antigen, were performed on 99 calves that died or were euthanized within 60 days after arrival. Major disease conditions identified included fibrinosuppurative bronchopneumonia (49%), caseonecrotic bronchopneumonia or arthritis (or both) caused by Mycoplasma bovis (36%), viral respiratory disease (19%), BVDV-related diseases (21%), Histophilus somni myocarditis (8%), ruminal bloat (2%), and miscellaneous diseases (8%). Viral infections identified were BVDV (35%), bovine respiratory syncytial virus (9%), bovine herpesvirus-1 (6%), parainfluenza-3 virus (3%), and bovine coronavirus (2%). Bacteria isolated from the lungs included M. bovis (82%), Mycoplasma arginini (72%), Ureaplasma diversum (25%), Mannheimia haemolytica (27%), Pasteurella multocida (19%), H. somni (14%), and Arcanobacterium pyogenes (19%). Pneumonia was the most frequent cause of mortality of beef calves during the first 2 months after arrival in feedlots, representing 69% of total deaths. The prevalence of caseonecrotic bronchopneumonia caused by M. bovis was similar to that of fibrinosuppurative bronchopneumonia, and together, these diseases were the most common causes of pneumonia and death. M. bovis pneumonia and polyarthritis has emerged as an important cause of mortality in Ontario beef feedlots. PMID:16566254

  12. Correlations between computed tomography findings and clinical manifestations of Streptococcus pneumoniae pneumonia

    International Nuclear Information System (INIS)

    The aim of this study was to characterize the imaging features and compare computed tomography (CT) findings with clinical features of patients with Streptococcus pneumoniae pneumonia. We retrospectively reviewed 75 patients (44 men, 31 women; mean age 67 years) diagnosed with S. pneumoniae pneumonia who underwent chest CT scanning at our institution between January 2007 and August 2008. Diagnoses were based on detection of the S. pneumoniae antigen in urine. Chest CT scans revealed abnormalities in all patients. The predominant opacity patterns were an airspace pneumonia pattern (48%) and a bronchopneumonia pattern (48%), followed by an interstitial pneumonia pattern (4%). Consolidation was observed most frequently (84%) followed by ground glass opacity (82.7%), bronchial wall thickening (61.3%), and centrilobular nodules (49.3%). Airway dilatation (21.6%), pleural effusion (33.3%), lymphadenopathy (34.8%), and pulmonary emphysema (21.3%) were also observed. Pulmonary emphysema was significantly less frequent in patients with the bronchopneumonia pattern than in those without (p=0.007). The clinical features and CT findings did not differ significantly. CT image analysis showed that patients with S. pneumoniae pneumonia exhibited the bronchopneumonia and airspace pneumonia patterns with equal frequency. Bronchopneumonia pattern was less common in patients with preexisting emphysema. (author)

    Full Text Available Since hospitals are an important and integral part of the overall health delivery system, this study was carried out to measure the effectiveness of this institution within the system. The records of 633 hospitalized patients in the pediatrics ward of Ghaem Hospital in Mashhad during 1357 (21 March 1978-20 March 1979 has been consulted. More than half of the patients were hospitalized with the following diagnoses: Bronchopneumonia, Gastroentritis, Septicemia, and Malnutrition. Bronchopneumonia peaked in winter, whereas Gastroentritis and Malnutrition peaked in summer. Most of the hospitalized patients were male and the malnutrition was limited to the pre-school children of 1-6 years of age. The importance of these findings in development and utilization of the health delivery system has been discussed and considering the preventable nature of the above mentioned diseases, development and expansion of primary health care activities has been stressed.

  14. The X-ray analysis of pulmonary manifestations in acute aspiration of trichlorethane

    International Nuclear Information System (INIS)

    Objective: To discuss the X-ray pulmonary changes in patients with acute aspiration of trichlorethane. Methods: Among 48 cases with acute aspiration of trichlorethane, 7 were male and 41 female, with ages ranged from 5.5 to 50 years old, mean age was 13.5 years old. 4 patients were diagnosed as mild acute intoxication, 22 as aspirating reaction, and 22 as uncomfortable reaction. And chest radiography was performed in all the cases. Results Pneumonia and bronchopneumonia was found in 4 cases with acute intoxication, inflammation around bronchial branches in 22 cases with aspirating reaction. The other cases were negative findings. Conclusions: Acute aspiration of trichlorethane may cause pneumonia, bronchopneumonia and inflammation around bronchial branches, which can be detected by chest radiography. (authors)

    The authors report on three autopsy cases in which the findings at the death scene gave rise to the suspect of non-natural, in two cases even violent causes of death. The medico-legal and criminalistic investigations led to surprising results: Death was due to acute intoxication with narcotics, supposed delirium tremens and a suicide attempt in the presence of bronchopneumonia. External force was ruled out in all three fatalities by cooperative work of police investigators and forensic medicine. PMID:12043435

    A 3-mo-old, male African hedgehog (Atelerix albiventris) was anorectic and lethargic for a period of 3 days prior to death. Necropys revealed lungs that were diffusely firm, dark red, and dorsally adhered by fibrinous tags to the pericardial sac. Histopathology revealed necrosuppurative bronchopneumonia with pulmonary abscesses and suppurative pericarditis and myocarditis. A Corynebacterium sp. was isolated from the lungs. We believe this is the first reported case of corynebacterial pneumonia in an African hedgehog. PMID:9577794

    Full Text Available Background: Therapeutic drug monitoring (TDM makes use of serum drug concentrations as an adjunct to decision-making. Preliminary data in our hospital showed that approximately one-fifth of all drugs monitored by TDM service were gentamicin. Objective: In this study, we evaluated the costs associated with providing the service in patients with bronchopneumonia and treated with gentamicin. Methods: We retrospectively collected data from medical records of patients admitted to the Hospital Universiti Sains Malaysia over a 5-year period. These patients were diagnosed with bronchopneumonia and were on gentamicin as part of their treatment. Five hospitalisation costs were calculated; (i cost of laboratory and clinical investigations, (ii cost associated with each gentamicin dose, (iii fixed and operating costs of TDM service, (iv cost of providing medical care, and (v cost of hospital stay during gentamicin treatment. Results: There were 1920 patients admitted with bronchopneumonia of which 67 (3.5% had TDM service for gentamicin. Seventy-three percent (49/67 patients were eligible for final analysis. The duration of gentamicin therapy ranged from 3 to 15 days. The cost of providing one gentamicin assay was MYR25, and the average cost of TDM service for each patient was MYR104. The average total hospitalisation cost during gentamicin treatment for each patient was MYR442 (1EUR approx. MYR4.02. Conclusion: Based on the hospital perspective, in patients with bronchopneumonia and treated with gentamicin, the provision of TDM service contributes to less than 25% of the total cost of hospitalization.

    Endogenous lipoid pneumonia (EnLP) is an uncommon non-life-threatening inflammatory lung disease that usually occurs in patients with conditions such as lung cancers, primary sclerosing cholangitis, and undifferentiated connective tissue disease. Here we report a case of EnLP in a paralytic and cachectic patient with bronchopneumonia after brain injury. A 40-year-old man experienced a severe brain injury in an automobile accident. He was treated for 1 month and his status plateaued. However, he became paralyzed and developed cachexia and ultimately died 145 days after the accident. Macroscopically, multifocal yellowish firm nodules were visible on scattered gross lesions throughout the lungs. Histologically, many foam cells had accumulated within the alveoli and alveolar walls accompanied by a surrounding interstitial infiltration of lymphocytes. The findings were in accordance with a diagnosis of EnLP. Bronchopneumonia was also noted. To our knowledge, there have been few reports of EnLP associated with bronchopneumonia and cachexia after brain injury. This uncommon pathogenesis should be well recognized by clinicians and forensic pathologists. The case reported here should prompt medical staff to increase the nutritional status and fight pulmonary infections in patients with brain injury to prevent the development of EnLP. PMID:26097618

    2007-12-01

    Parasites were collected from 107 harbour seals ( Phoca vitulina) found on the coasts of Schleswig-Holstein, Germany, between 1997 and 2000. The prevalence of the parasites and their associated pathology were investigated. Eight species of parasites, primarily nematodes, were identified from the examined organs: two anisakid nematodes ( Pseudoterranova decipiens (sensu lato) , Contracaecum osculatum (sensu lato)) from the stomach, Otostrongylus circumlitus (Crenosomatidae) and Parafilaroides gymnurus (Filaroididae) from the respiratory tract, one filarioid nematode ( Acanthocheilonema spirocauda) from the heart, two acanthocephalans, Corynosoma strumosum and C. semerme (Polymorphidae), from the intestine and an ectoparasite, Echinophthirius horridus (Anoplura, Insecta). Lungworm infection was the most prominent parasitological finding and secondary bacterial bronchopneumonia the most pathogenic lesion correlated with the parasites. Heavy nematode burdens in the respiratory tract were highly age-related and more frequent in young seals. A positive correlation was observed between high levels of pulmonary infection and severity of bronchopneumonia. The prevalence of lungworms in this study was higher than in seals that died during the 1988/1989 Phocine Distemper Virus epidemic, and the prevalence of acanthocephalans and heartworms had decreased compared to findings from the first die-off.

    Full Text Available Cytoplasmic inclusion bodies in adrenal medullary chromaffin cells have been described in various species including humans. These inclusions are believed to be related to certain infectious, toxic and neurodegenerative diseases. No reports concerning such adrenal inclusions have been described in bovines. Adrenal glands from twenty bovines were evaluated in a retrospective study. Seven of these exhibited inclusions - three cases of rabies, two cases of chronic suppurative bronchopneumonia, one case of chronic suppurative peritonitis, and one case of gangrenous mastitis. The inclusions were present in higher numbers especially in cases of rabies and also in one case of chronic suppurative bronchopneumonia. The inclusions were intracytoplasmic, eosinophilic, rounded, single or multiple, of various sizes, strongly stained by PAS and were present in higher numbers in the external layer of the adrenal medulla. The inclusions were negative when subjected to immunohistochemistry for detection of viral antigens in the cases of rabies. Although inclusion bodies were present in adrenal glands devoid of other histological alterations, they were more abundant in cases in which the adrenal gland had other alterations. The correlation between certain diseases and the development of inclusion bodies is not known, which highlights the importance of further studies on these inclusions in adrenal glands of bovines.

    2007-01-01

    Full Text Available The timely supply of newborn calves with optimal quantities of colostrum has a key role in the process of immune protection in the early phase of their lives. Passively acquired antibodies can protect the digestive organs from infection caused by E.coli bacteria, and it seems also from the appearance of diseases of the respiratory tract. These examinations were performed on a cattle farm where bronchopneumonia was one of the most significant health problems, and a group of 39 calves were selected for the investigations. The calves were fed with their mothers’ colostrum after birth, and then with collective milk. Immunoglobulin concentration was determined in blood samples taken during the postcolostral period, with the method using zinc-sulphate. At the age of 40 days, the calves were administered a polyvalent inactivated vaccine, and revaccinated 20 days after that (Vibak, Veterinary Department Subotica. In 74.34% calves, the immunoglobulin G concentration ranged from 26 to 40 g/l. In 25.66% calves, the immunoglobulin concentration was lower, from 8 to 25 g/l. The calves found to have a lower concentration of immunoglobulin in blood contracted bronchopneumonia more frequently, and the outcome of the disease in some cases was mortality, even.

    Background. Mother's milk is the best for the babies. Protective and preventive role of breast milk was evaluated in this study by assessing the relation of type of feeding and duration of hospital stay or morbidity. Methods. This prospective study was conducted in a tertiary care hospital and 232 infants in the age group of 14 weeks to 6 months formed the sample. There are two groups of infants, that is, one for breastfed and one for top fed infants. Statistical analysis was done and results were calculated up to 95% to 99% level of significance to find effect of feeding pattern on hospital stay due to various diseases and morbidity. Results. Prolonged hospital stay, that is, >7 days, was lesser in breastfed infants and results were statistically significant in case of gastroenteritis (p value < 0.001), bronchopneumonia (p value = 0.0012), bronchiolitis (p value = 0.005), otitis media (p value = 0.003), and skin diseases (p value = 0.047). Lesser morbidity was seen in breastfed infants with gastroenteritis (p value 0.0414), bronchopneumonia (p value 0.03705), bronchiolitis (p value 0.036706), meningitis (p value 0.043), and septicemia (p value 0.04). Conclusions. Breastfed infants have shorter hospital stay and lesser morbidity in regard to various diseases as compared to top fed infants.

    Pneumonia is an acute inflammation of the lower respiratory tract. Lower respiratory tract infection is a major cause of mortality worldwide. Pneumonia is most common at the extremes of life. Predisposing factors in children include an under-developed immune system together with other factors, such as malnutrition and over-crowding. In adults, tobacco smoking is the single most important preventable risk factor. The commonest infecting organisms in children are respiratory viruses and Streptoccocus pneumoniae. In adults, pneumonia can be broadly classified, on the basis of chest radiographic appearance, into lobar pneumonia, bronchopneumonia and pneumonia producing an interstitial pattern. Lobar pneumonia is most commonly associated with community acquired pneumonia, bronchopneumonia with hospital acquired infection and an interstitial pattern with the so called atypical pneumonias, which can be caused by viruses or organisms such as Mycoplasma pneumoniae. Most cases of pneumonia can be managed with chest radiographs as the only form of imaging, but CT can detect pneumonia not visible on the chest radiograph and may be of value, particularly in the hospital setting. Complications of pneumonia include pleural effusion, empyema and lung abscess. The chest radiograph may initially indicate an effusion but ultrasound is more sensitive, allows characterisation in some cases and can guide catheter placement for drainage. CT can also be used to characterise and estimate the extent of pleural disease. Most lung abscesses respond to medical therapy, with surgery and image guided catheter drainage serving as options for those cases who do not respond. PMID:21088086

In order to reduce the number of infected children, increasing emphasis should be placed on preventing mother to child transmission programs with the use of antiretroviral medications in the pregnant woman during pregnancy and at delivery and, starting immediately after birth for the exposed infant. Here, we present the case of a 60-day-old infant heavily immunocompromised due to an extremely high viral burden of HIV, which was acquired perinatally from an undiagnosed and untreated mother, leading to severe bronchopneumonia, sepsis, septic shock and death.

    Full Text Available Aspergillus is a ubiquitous dimorphic fungus that causes a variety of human diseases ranging in severity from trivial to life-threatening, depending on the host response. An intact host defence is important to prevent disease, but individuals with pre-existing structural lung disease, atopy, occupational exposure or impaired immunity are susceptible. Three distinctive patterns of aspergillus-related lung disease are recognized: saprophytic infestation of airways, cavities and necrotic tissue; allergic disease including extrinsic allergic alveolitis, asthma, allergic bronchopulmonary aspergillosis, bronchocentric granulomatosis and chronic eosinophilic pneumonia; and airway and tissue invasive disease -- pseudomembranous tracheobronchitis, acute bronchopneumonia, angioinvasive aspergillosis, chronic necrotizing aspergillosis and invasive pleural disease. A broad knowledge of these clinical presentations and a high index of suspicion are required to ensure timely diagnosis and treatment of the potentially lethal manifestations of aspergillus-related pulmonary disease. In the present report, the clinical, radiographic and pathological aspects of the various aspergillus-related lung diseases are briefly reviewed.

    Full Text Available This study is a retrospective examination of diseases in collared peccaries that were diagnosed by the Veterinary Pathology Laboratory, Universidade Federal Rural do Semiárido. Necropsy and histological examination were performed from 2005 to 2010. Of the 50 necropsied collared peccaries, 24% died due to restraint and capture myopathy; 18% died from trauma; and the remainder was diagnosed with splenic hemangioma (6%, enterolithiasis (6%, gastritis (6%, gastric ulcer (4%, intestinal volvulus (4%, gastric volvulus (2%, mammary carcinoma (2%, polycystic kidney disease (2%, pyometra (2%, and suppurative bronchopneumonia (2%. Twelve animals remained undiagnosed, seven of which (14% were in advanced autolytic condition and five of which (10% had no gross or microscopic lesions that were compatible with disease. This paper describes illnesses that have not been reported in the collared peccary, focusing on their clinical and pathological aspects.

    1) Twenty-one raccoons and 3 red foxes were collected from areas where suspected rabies occurred. All were found to be nonrabid. 2) Distemper was diagnosed in 14 of the 21 raccoons by demonstrating intracytoplasmic and intranuclear inclusions in the brain and visceral tissues. Two of the 3 foxes were considered to have distemper; the clinical signs were typical and mouse inoculation tests were negative for rabies. 3) Deaths of the other 7 raccoons were attributed to: leishmaniasis 1, gastritis 1, bronchopneumonia 1, parasitism 2, car injury 1; 1 showed no significant lesions. The death of 1 fox was attributed to parasitism. 4) Distemper may be a frequent cause of death in raccoons and foxes, in epizootics which simulate rabies.

    beta-Mannosidase deficiency was demonstrated in fibroblasts of a girl who showed severe psychomotor retardation, bone deformities and gargoylism and recurrent skin and respiratory infections and who died at 20 years of age from bronchopneumonia. This first demonstration of a female patient confirms the autosomal recessive inheritance of beta-mannosidosis. Further investigation of this gypsy family revealed beta-mannosidosis in an older brother with a milder manifestation of gargoyl facial dysmorphology, mental retardation, hearing impairment and recurrent infections. beta-Mannosidase activity was completely deficient in his cultured skin fibroblasts, leukocytes and plasma. In urine a characteristic disaccharide was present. Heterozygote levels of beta-mannosidase were found in fibroblasts and/or plasma of the parents and one sister. PMID:2079835

    International Nuclear Information System (INIS)

    An observational, descriptive and cross-sectional study was carried out in 55 patients admitted to the Internal Medicine Service of 'Conrado Benitez Garcia' University Oncology Hospital in Santiago de Cuba with clinical diagnosis of lung cancer, from December 2008 to November 2009, to characterize them according to variables of interest for research. Among the main results were predominance of male sex, age group between 60-69 years, smoking habit, and chronic bronchitis as past medical history, and acute bronchopneumonia as clinical form, lung infiltrative peripheral image as tomographic finding and adenocarcinoma in stages IIIa and IIIb as tissue confirmation, among others. There was an excellent consistency among clinical, imagenological and pathological findings.(author)

    2006-07-01

    As part of a species recovery program, 129 Canada lynx (Lynx canadensis) originating from British Columbia, the Yukon, Manitoba, and Quebec, Canada, and Alaska, USA, were reintroduced to southwestern Colorado, USA, from 1999 to 2003. Of 52 lynx mortalities documented by October 2003, six lynx, including a female and her 5-mo-old kitten, had evidence of Yersinia pestis infection as determined by fluorescent antibody test and/or culture. Postmortem findings in these lynx were characterized by pneumonia, ranging from acute suppurative pneumonia, to multifocal necrotizing pneumonia, to fibrinous bronchopneumonia. Histopathologic examination of lung revealed multiple areas of inflammation and consolidation, areas of edema and hemorrhage, and bacteria surrounded by extensive inflammation. Spleens had severe lymphoid depletion and hypocellular red pulp. Lymphadenomegaly was observed in only one plague-affected lynx. We hypothesize that these Canada lynx were exposed to Y. pestis by infected prey, and these are the first reports of plague in this species. PMID:17092896

  12. Bronchial and pulmonary scintigraphy with radioactively marked aerosols

    International Nuclear Information System (INIS)

    In 97 patients with bronchitis, bronchial asthma, tuberculosis, sarcoidosis, pneumoconiosis, or tumors the mucociliary clearance and/or deposit pattern after inhalation of radioactively marked aerosols (1 mCi 99m Tc sulfur colloid) was studied. Normal values of the mucociliary 30 min. clearance for the central bronchial/lung periphery are 21%/15%. There was a decreased clearance with bronchitis (11/8%), bronchial asthma, emphysema, tuberculosis, sarcoidosis, trachiobronchial amyloidosis, pleural scarring or interstitial pneumona. Increased clearance (29/19%) was shown with pneumoconiosis. The correlation of deposit pattern and disease, for example, bronchitis, bronchial asthma, bullous emphysema, pleural scarring, partial lung resection, bronchopneumonia, or bronchial restriction, is described. In comparison of aerosol scintigraphy to perfusion scintigraphy and ventilation with gaseous xenon, the aerosol scintigraphy is superior to xenon for certain indications. The aerosol particles, which are larger in comparison to xenon, settle easier by obstructions or flow variations and thereby give better clinical indications of regional differences. (orig.)

  13. Pneumatisation of the maxillary sinus in normal and symptomatic children

    International Nuclear Information System (INIS)

    The pattern of pneumatisation and normal width of the maxillary sinus in 191 Nigerian infants and children whose age range was 6 months to 14 years was determined. Fifty-four percent of children with no respiratory tract or sinus infection had opaque maxillary sinus. A figure of 44.5% was obtained amongst children with suspected bronchopneumonia. Only 41.5% of suspected cases of sinusitis, acute and chronic middle ear disease had opaque sinus. The highest rate of sinus opacity was seen in children under 2 years who were asymptomatic. The mean maximal width of normally aerated sinus was 8.74 mm for children under 2 years, 16.5 mm for 3-6 years, 21.5 mm for 7-11 years and 25 mm for children 12 years and above. We conclude that maxillary sinus opacity in our experience is an unreliable index for the diagnosis of sinusitis in children. (orig.)

  14. Total lymphoid irradiation in refractory systemic lupus erythematosus

    International Nuclear Information System (INIS)

    In two patients with systemic lupus erythematosus, conventional therapy was considered to have failed because of persistent disease activity and unacceptable side effects. Both were treated with total lymphoid irradiation without clinical benefit, despite adequate immunosuppression as documented by markedly reduced numbers of circulating T lymphocytes and T-lymphocyte-dependent proliferative responses in vitro. The first patient developed herpes zoster, gram-negative septicemia, neurologic symptoms, and deterioration of lupus nephritis. The second patient developed massive bronchopneumonia, necrotic cutaneous lesions, and progressive nephritis and died 2 weeks after completion of radiotherapy. These observations, although limited to two patients, indicate that total lymphoid irradiation in patients with severe systemic lupus erythematosus should be regarded as strictly experimental

    Oligonucleotide probes targeting 16S ribosomal RNA were designed for species-specific identification of the porcine mycoplasmas Mycoplasma hyopneumoniae, Mycoplasma hyorhinis and Mycoplasma hyosynoviae using a fluorescent in situ hybridisation assay. The specificity of the probes was evaluated...... using pure cultures as well as porcine tissue sections with artificial presence of mycoplasma, and the probes were found specific for the target organisms. The assay was applied on sections of 28 tissue samples from pigs infected with one or more of the three Mycoplasma species as determined by...... cultivation. M. hyopneumoniae and M. hyorhinis were identified in accordance with cultivation in lung sections, from nine pigs affected by catarrhal to purulent bronchopneumonia. Likewise, in eight cases of fibrinous pericarditis, M. hyopneumoniae, M. hyorhinis and M. hyosynoviae were the infectious agents...

    Full Text Available In February 2012, a reproductive group of 60 adult blackbucks (Antilope cervicapra from Veracruz, Mexico was relocated to hunting units in eastern and northeastern Mexico. Seven individuals died due to hemorrhagic parasitic, abomasitis and enteritis caused by Haemonchus spp., Setaria spp., and Trichostrongylids. Deaths were associated with hepatic necrosis, bilateral congestive distention of heart and fibrinonecrotic bronchopneumonia. Also Anaplasma marginale was identified. The blackbucks’ population displayed a general mortality rate of 11.67%, where 25% of total male and 9.62% of total female died. The mortality was controlled by segregation of all remaining blackbucks and the treatment for internal and external parasites (biting flies and ticks. After the treatment, no fatality cases related to parasitosis were recorded. The results presented here exhibit the high relevance of parasitosis as possible factor risk in the survival of tis specie.

    Full Text Available BACKGROUND: Pneumonia remains the number one killer of children, taking the lives of 1.3 million in 2011 alone. More than 99% of all pneumonia deaths occur in developing countries. The majority of pneumonia cases are preventable and treatable, but clinical diagnosis is highly fallible in many cases and the frequency of morbid state is best assessed by post-mortem examination that may reveal diagnosis which may not be suspected clinically or may, in some way, discredit. AIMS: 1. To ascertain various pulmonary lesions in paediatric deaths. 2. To find incidence of pulmonary lesions. 3. To study the incidence of pulmonary tuberculosis, 4. To find incidence of pulmonary pathology directly and indirectly contributing to the death. SETTINGS: Lokmanya Tilak Municipal General Hospital, Sion, Mumbai. DESIGN: A retrospective observational study. METHODS AND MATERIAL: In this study pediatric age group of (0-15 years admitted in IPCU,NICU and Pediatric, Medicine and Surgery unit are included from the period of 2006-2013. The lung pathology in various diseases entities were studied and co-related with age, sex and clinical history. RESULTS: Of total 3606 autopsies, 642 were pediatric autopsies i.e. 17.8% of all autopsies, and 111 were neonatal autopsies. Of 642, 531(82.7% had primary lung pathology and 157(24.4% had secondary lung pathology. The common age group affected is < 5 years. Bronchopneumonia was the commonest pathology observed as primary lung pathology. Interstitial/viral pneumonia was 2nd most common of primary lung pathology Infective pathology was the most common lesions, of which bronchopneumonia was the most common pathology observed and tuberculosis contributed to 3%of primary lung pathologies. CONCLUSION: The most common lung lesion in pediatric age is infections, which are preventable and curative with appropriate measures. This study will help to improve mother child health services

    Bordetella bronchiseptica frequently causes nonfatal tracheobronchitis, but its role in fatal pneumonia is less recognized. Our study evaluated histologic identification of cilia-associated bacteria as a method for diagnosis of B. bronchiseptica pneumonia. Cases of fatal bronchopneumonia were studied retrospectively, excluding neonates and cases of aspiration pneumonia, minor lung lesions, or autolysis. The study population comprised 36 canine and 31 feline cases of bronchopneumonia. B. bronchiseptica was identified in 8 of 36 canine and 14 of 31 feline cases based on immunohistochemistry (IHC) using serum from a rabbit hyperimmunized with pertactin, PCR testing (Fla2/Fla12), and/or bacterial culture data when available. Of these, IHC was positive in 4 canine and 7 feline cases, PCR was positive in 8 canine and 14 feline cases, and B. bronchiseptica was isolated in 2 of 5 canine and 3 of 9 feline cases tested. Examination of histologic sections stained with hematoxylin and eosin revealed bronchial cilia-associated bacteria in 4 of 36 canine and 5 of 31 feline cases; these were all positive by IHC and PCR. The presence of cilia-associated bacteria had been noted in the pathology report for only 2 of these 9 cases. Thus, the presence of cilia-associated bacteria seems frequently overlooked by pathologists, but is a diagnostically significant feature of B. bronchiseptica pneumonia. A specific diagnosis of B. bronchiseptica pneumonia is important because it suggests primary or opportunistic bacterial pneumonia rather than aspiration pneumonia, and because of the risk of animal-to-animal transmission of B. bronchiseptica, the availability of vaccines for disease prevention, and the potential zoonotic risk to immunocompromised pet owners.

    Full Text Available The aim of the present study was to evaluate the diagnostic value of Acute Phase Proteins (APP, lipid profiles and proinflammatory cytokines in healthy and bronchopneumonic water buffalo calves. Therefore, sixty water buffalo calves (9±1 month old, 175±15 kg were divided into two equal groups, the first group represented healthy, control, calves whereas calves of the second group were affected with bronchopneumonia. Total leukocytic and differential counts were determined. Serum total protein, albumin, Triacylglyceol (TAG, low density lipoprotein cholesterol (LDL-c, High Density Lipoprotein cholesterol (HDL-c, Total cholesterol, Alanine Amino Transferase (ALT, Aspartate Amino Transferase (AST, Alkaline Phosphatase (ALP, Fibrinogen (Fb, Haptaglobin (Hp, Serum Amyloid A (SAA, Tumor Necrosis Factor-alpha (TNF-α, Interleukins (IL1β, IL-12 and Interferon-gamma (IFN-γ were also determined. In addition, Bronchoalveolar Lavage (BAL was collected and analyzed. The present findings indicated that, total leukocytic and neutrophils counts were significantly (p<0.05 higher in pneumonic water buffalo calves compare with control. The examined biochemical parameters were significantly (p<0.05 increased in pneumonic calves except for total protein, albumin, cholesterol and HDL-c which were significantly (p<0.05 lower compare with control. Serum concentrations of investigated APP and proinflammatory cytokines were significantly (p<0.05 higher in pneumonic water buffalo calves than those of control. The present study demonstrated that, APP, lipid profile and proinflammatory cytokines perhaps served as biomarkers of bronchopneumonia in water buffalo calves. However, future studies with higher baseline sampling are still needed to establish and validate reference values for APP and cytokines in water buffalo calves.

    Full Text Available Zoo animals, including tigers, have been reported to suffer from barbiturate intoxication, with pentabarbitone being most commonly recorded. Clinical signs range from mild ataxia to general anaesthesia with recovery over hours to days with several factors affecting hepatic barbiturate metabolism and tissue partitioning. Botulism is an often fatal intoxication in man, animals, birds and certain fish. The occurrence in carnivores is uncommon to rare, with only 2 reports found of botulism in felids. This report relates to 3 adult captive cohabiting tigers that simultaneously developed signs of abdominal discomfort, progressive ataxia, recumbency and comatose sleep resembling stage 2 anaesthesia, alternating with periods of distracted wakefulness and ataxic movements. These signs occurred 4 days after being fed the carcass of a horse that had ostensibly died of colic and not been euthanased. The male tiger that was the dominant animal in the feeding hierarchy was worst affected and had to be given intravenous fluids. The female that was lowest in hierarchy was unaffected. After 48-72 hours of treatment at the Onderstepoort Veterinary Academic Hospital the females could eat and made an uneventful recovery. The male tiger showed partial recovery but died during the night a few hours after drinking water on his return to the owner. Necropsy revealed severe oesophageal dilation and impaction with decaying grass; some of this material and water were present in the pharynx and trachea, and had been aspirated causing acute widespread bronchopneumonia. Colon content tested negative for common pesticides but, together with liver, tested positive for barbiturate. Serum taken on the day of admission had tested negative for barbiturate and the residual serum from the 3 animals later tested negative for botulinum toxin. Colon and oesophageal content from the male at necropsy were positive for Clostridium botulinum toxin type C by the mouse bioassay

    2012-10-01

    Full Text Available Abstract Niemann-Pick disease type C (NP-C is a rare neurovisceral disease characterised by progressive neurological deterioration and premature death, and has an estimated birth incidence of 1:120,000. Mutations in the NPC1 gene (in 95% of cases and the NPC2 gene (in approximately 4% of cases give rise to impaired intracellular lipid metabolism in a number of tissues, including the brain. Typical neurological manifestations include vertical supranuclear gaze palsy, saccadic eye movement abnormalities, cerebellar ataxia, dystonia, dysmetria, dysphagia and dysarthria. Oropharyngeal dysphagia can be particularly problematic as it can often lead to food or fluid aspiration and subsequent pneumonia. Epidemiological data suggest that bronchopneumonia subsequent to food or fluid aspiration is a major cause of mortality in NP-C and other neurodegenerative disorders. These findings indicate that a therapy capable of improving or stabilising swallowing function might reduce the risk of aspiration pneumonia, and could have a positive impact on patient survival. Miglustat, currently the only approved disease-specific therapy for NP-C in children and adults, has been shown to stabilise key neurological manifestations in NP-C, including dysphagia. In this article we present findings from a systematic literature review of published data on bronchopneumonia/aspiration pneumonia as a cause of death, and on the occurrence of dysphagia in NP-C and other neurodegenerative diseases. We then examine the potential links between dysphagia, aspiration, pneumonia and mortality with a view to assessing the possible effect of miglustat on patient lifespan.

    Full Text Available Abstract Background M. pneumoniae pneumonia (MP has been reported in 10-40% of community-acquired pneumonia cases. We aimed to evaluate the difference of clinical features in children with MP, according to their age and chest radiographic patterns. Methods The diagnosis of MP was made by examinations at both admission and discharge and by two serologic tests: the indirect microparticle agglutinin assay (≥1:40 and the cold agglutinins titer (≥1:32. A total of 191 children with MP were grouped by age: ≤2 years of age (29 patients, 3-5 years of age (81 patients, and ≥6 years of age (81 patients. They were also grouped by pneumonia pattern: bronchopneumonia group (96 patients and segmental/lobar pneumonia group (95 patients. Results Eighty-six patients (45% were seroconverters, and the others showed increased antibody titers during hospitalization. Among the three age groups, the oldest children showed the longest duration of fever, highest C-reactive protein (CRP values, and the most severe pneumonia pattern. The patients with segmental/lobar pneumonia were older and had longer fever duration and lower white blood cell (WBC and lymphocyte counts, compared with those with bronchopneumonia. The patient group with the most severe pulmonary lesions had the most prolonged fever, highest CRP, highest rate of seroconverters, and lowest lymphocyte counts. Thrombocytosis was observed in 8% of patients at admission, but in 33% of patients at discharge. Conclusions In MP, older children had more prolonged fever and more severe pulmonary lesions. The severity of pulmonary lesions was associated with the absence of diagnostic IgM antibodies at presentation and lymphocyte count. Short-term paired IgM serologic test may be mandatory for early and definitive diagnosis of MP.

    presented reduced growth rate, anorexia, lethargy, cough and dyspnea, especially after they were moved. High body temperature (40ºC in average was verified in some animals. Auscultation revealed moderate pulmonary crepitation and stertors. Pulmonary gross lesions were typical of lobular bronchopneumonia. Lung lesions were characterized by ventral-cranial consolidation in the majority of the cases. The color of affected pulmonary areas varied from diffuse dark red to mosaic pattern (dark red lobule intercalate by grayish lobule or diffusely grayish. The majority of the lungs had mucopurulent exsudate in the bronchial lumen that also drained from the parenchyma cut surface. Upon microscopy, the changes were characterized by purulent and histiocytic bronchopneumonia with necrotic foci. In some animals, there was BALT hyperplasia associated with perivascular and peribronchial plasma cells and lymphocytes infiltration in most of these cases. Bordetella bronchiseptica and Streptococcus spp. were the most frequently isolated bacteria. Immunohistochemistry evaluation demonstrated Mycoplasma hyopneumoniae on the luminal surface of bronchial and bronchiolar epithelial cells, and the DNA of bacteria was detected by PCR. This is the first report of bronchopneumonia in wild boars associated with M. hyopneumoniae infection.

    Pathological examination of stranded marine mammals provides information on the causes of mortality in their populations. Patterns of stranding and causes of death of dead-stranded seals on the Dutch coast were analyzed over a 30-year period (1979-2008). Stranding data (n=1,286) and post-mortem data (n=379) from common seals (Phoca vitulina) and grey seals (Halichoerus grypus) found dead, or that died before admission to rehabilitation, were obtained from the Seal Rehabilitation and Research Centre database. Data for the years 1988 and 2002, when mass mortality occurred due to phocine distemper virus epidemics, were excluded. Common seal stranding increased from one to nearly 100 per year over this period. This coincides with the increase in the number of common seals in Dutch waters over recent decades. Grey seal stranding increased gradually from one to about 40 per year over the period, reflecting recolonization of Dutch waters by this species. For both species, the trend in stranding of dead seals was found to be in line with that of seals observed in Dutch waters during aerial surveys and did not provide any indications of a relative change in the stranding rate of dead seals. The total monthly stranding rates peaked at more than 120 in June and July for common seals and at nearly 60 in January for grey seals. This coincides with the pupping periods of the two species. Besides phocine distemper, the most common causes of death in investigated common seals (n=286) were by-catch (confirmed and inferred) (19%), pup starvation (7%), intestinal volvulus (7%) and parasitic bronchopneumonia (6%). The most common causes of death in investigated grey seals (n=93) were by-catch (confirmed and inferred) (15%), pup starvation (11%) and trauma (5%). The relative occurrence of by-catch significantly decreased over time for grey seals, but not for common seals. Common seals were affected by infectious disease significantly more often than grey seals, mainly because of a

  8. SPECT perfusion lung scintigraphy in children with chronic pulmonary damage: Preliminary results of a prospective study

    International Nuclear Information System (INIS)

    The aim of this study was to describe SPECT perfusion lung scintigraphy findings in symptomatic children with chronic pulmonary damage. Material and Method: We studied 111 children (average age:3.9 yr, range:1 month- 15 yr, 61.3% boys) with chronic pulmonary pathology. The most common clinical diagnosis reported in this population were recurrent bronchopneumonia (45.9%), unknown origin chronic pulmonary damage (36.9%), chronic obstructed bronchitis (27.9%), adenovirus bronchopneumonia sequelae (27.9%) and bronchopulmonary dysplasia (14.4%). The SPECT lung perfusion scintigraphy (LS) was performed in a SMV DST XLi two headed gammacamera, 64x64 matrix, 32 steps of 15 sec each, using a HRLE collimator, after i.v. injection of a age-adjusted dose of Tc99m-MAA. The images were reconstructed using a iterative-post filter method and displayed in tomographic slices and 3D form. We took also planar images in frontal and posterior projections to assess the differential perfusion. The studies were separated according to scintigraphy findings and gender. Results: Ninety eight (88.3%) of realized LS were abnormal (59.2% boys). Fifty three (54.1%) of abnormal scans showed bilateral alterations, being this finding significantly (p:0.034) more frequent in boys (63.8% bilateral lesions) than in girls (40.0% bilateral lesions). When unilateral altered scans were analyzed, the right lung was more frequently affected than left lung (73.5% vs 26.5%) (p:0.002). Of whole abnormal group, 19.4% had diffuse perfusion alterations, 46.9% showed focal alterations and 33.7% had a mixed diffuse-focal pattern. In focal alterations group, the majority presented a segmental distribution (83.7%), being the more frequent localizations the right inferior lobe (39.8%), right upper lobe (34.7%) and left inferior lobe (34.7%). Sixteen patients (16,3%) had focal non-segmental alterations, being situated mainly in upper middle of right lung (47.6%). The range of differential perfusion quantification in

    This study aims to assess and compare copaiba oleoresin of Copaifera multijuga and 0.5% silver nitrate for the induction of pleurodesis in an experimental model. Ninety-six male Wistar rats were divided into three groups: control (0.9% saline solution), copaiba (copaiba oil), and silver nitrate (0.5% silver nitrate). The substances were injected into the right pleural cavity and the alterations were observed macroscopically and microscopically at 24, 48, 72, and 504 h. The value of macroscopic alterations grade and acute inflammatory reaction grade means was higher in the 24 h copaiba group in relation to silver nitrate. Fibrosis and neovascularization means in the visceral pleura were higher in 504 h copaiba group in relation to the silver nitrate group. The grade of the alveolar edema mean was higher in the silver nitrate group in relation to the copaiba group, in which this alteration was not observed. The presence of bronchopneumonia was higher in the 24 h silver nitrate group (n = 4) in relation to the copaiba group (n = 0). In conclusion, both groups promoted pleurodesis, with better results in copaiba group and the silver nitrate group presented greater aggression to the pulmonary parenchyma. PMID:24999484

    Diagnostic probability of community-acquired pneumonia (CAP) depends on data related to age and clinical and radiological findings. The critical evaluation of data in the literature leads to the following conclusions: 1) the prevalence of CAP in a given population with acute respiratory disease is 5% in outpatients and 10% in an emergency care unit. This could be as low as 2% in young people and even higher than 40% in hospitalized elderly patients; 2) the collection of clinical data is linked to the way the patient is examined and to the expertise of the clinician. The absolute lack of "vital signs" has a good negative predictive value in CAP; presence of unilateral crackles has a good positive predictive value; 3) there is a wide range of X-ray abnormalities: localized alveolar opacities; interstitial opacities, limited of diffused. The greatest radiological difficulties are encountered in old people with disorders including chronic respiratory or cardiac opacities and as a consequence of the high prevalence of bronchopneumonia episodes at this age; 4) among patients with lower respiratory tract (LRT) infections, the blood levels of leukocytes, CRP and procalcitonine are higher in CAP patients, mainly when their disease has a bacterial origin. Since you have not a threshold value reliably demonstrated in large populations with LRT infections or acute respiratory disease, presence or absence of these parameters could only be taken as a slight hint for a CAP diagnosis.

    Anthrax, a disease of mammals (including humans), is caused by a spore-forming Gram-positive bacilli called Bacillus anthracis. Anthrax is one of the oldest threats to humanity, and remains endemic in animals in many parts of the world. The incidence of anthrax has decreased in developed countries, but it remains a considerable health problem in developing countries. The disease is transmitted to humans by contact with sick animals or their products, such as wool, skin, meat etc. Capsular polypeptide and anthrax toxin are the principal virulence factors of B. anthracis. Anthrax toxin consists of three proteins called protective antigen, edema factor, and lethal factor, each of which is nontoxic but acts synergistically. Human anthrax has three major clinical forms: cutaneous, inhalational, and gastrointestinal. The diagnosis is easily established in cutaneous cases, characterized by black eschar. Severe intoxication and collapse during the course of bronchopneumonia or hemorrhagic enteritis should prompt suspicion of anthrax. Treatment with antibiotics is mandatory. If untreated, anthrax in all forms can lead to septicemia and death. Recently, considerable attention has been focused on the potential for B. anthracis to be used in acts of biological terrorism. The ease of laboratory production and its dissemination via aerosol led to its adoption by terrorists, as shown by recent events in the USA. A good knowledge of anthrax, its epidemiology, pathogenesis, clinical forms and potential as a biological weapon is essential for timely prevention and treatment. This review summarizes the current knowledge on anthrax. PMID:14586293

    Hematological findings in a female killer whale (Orcinus orca) undergoing rehabilitation after sudden severe anorexia revealed continuing increases in serum lactate dehydrogenase and aspartate aminotransferase activities as well as fibrinogen concentration. Serologic evidence of herpesvirus infection and skin vesicles were detected 2 weeks into the treatment regimen of antibiotics and corticosteroids. The whale showed signs of improvement after treatment with anti-herpesvirus drugs, but sudden severe anorexia reappeared, along with marked elevation of fibrinogen concentration that continued until the death. Postmortem examination revealed multiple light tan foci of necrosis in the skeletal and cardiac muscles, and lung consolidation. Microscopic findings indicated disseminated fungal granulomas in the skeletal and cardiac muscles, as well as myocarditis, mycotic embolic thromboarteritis of cardiac blood vessels, and bronchopneumonia with numerous typical Aspergillus-like fungi. Mucor-like structures in granulomas in the heart and skeletal muscle and Aspergillus-like fungi in the lungs were identified using periodic acid-Schiff, Gomori methenamine silver stain, and immunohistochemistry. The present case involves dual infection with Mucor and Aspergillus species in a killer whale with concurrent herpesvirus. PMID:22362957

  14. Pulmonary perfusion scintigraphy in children with chronic pulmonary damage: Preliminary results from application of the SPECT technique

    International Nuclear Information System (INIS)

    The aim was to describe lung perfusion SPECT (LPS) findings in children with chronic pulmonary damage. Material and Method: We revised 106 LPS of children (age:3.9 ± 3.3 yr) with chronic pulmonary damage, performed with a two headed gamma camera. The most common clinical diagnosis were adenovirus bronchopneumonia sequelae (ADV)(29%), unknown origin chronic pulmonary damage (UOPD) (21%), bronchopulmonary dysplasia (BPD)(15%), and chronic obstructed bronchitis (COB)(14%). Severity of pulmonary alterations were evaluated using a Score, which considered extent and type of lung involvement and differential pulmonary perfusion. Pattern of involvement and Score were correlated with diagnosis and gender. Results: Ninety one percent (96/106) of LPS were abnormal (62% boys). Fifty two (54%) showed bilateral alterations, being this finding (p:0.019) more frequent in boys. ADV group showed mainly a mixed bilateral pattern (35%), UOPD a focal unilateral pattern (32%), COB a diffuse unilateral pattern (33%), and BPD a normal pattern (25%). Miscellaneous and UOPD showed the highest score values, and BPD and COB the lowest ones. Conclusion: In this population, LPS is abnormal in high proportion, with some differential characteristics according gender and original diagnosis (au)

    In the present study, a total of 14 (73.68%) cases of abortions and two (100%) cases of still births were detected positive for Trypanosoma evansi infection by wet and dry blood smear examination and fetal tissue PCR in camels of an organized farm. The abortions in infected dams were recorded from 8 to 11.5 month of gestation, however majority occurred during 9th to 10th month. The important laboratorial findings in infected dams were anemia, hypoglycemia, hyperproteinemia and leukocytosis. At necropsy the T. evansi infected aborted and still born fetuses showed subcutaneous edema, presence of moderate amount of dark red hemolysed blood in thoracic and abdominal cavity, bronchopneumonia, hepatic necrosis and acute congestion in all vital organs. Microscopically, there was severe congestion, thickening of bronchial and alveolar wall and mononuclear infiltration in the fetal lung, necrotic and degenerative changes in the liver, nephritis along with severe congestion and tubular necrosis in the kidneys and necrotic and degenerative changes and congestion of capillaries in the brain. The T. evansi DNA was detected by PCR from blood, lung, spleen, liver, kidney and brain of all the infected aborted and still born fetuses. The results of the study indicated that T. evansi can cross placental barrier and cause pathological events in the fetus resulting into abortion or still birth in pregnant camels. PMID:27078656

    Francisella tularensis is a facultative intracellular bacterium that causes tularemia in humans and animals. Epidemiology of tularemia worldwide is often associated with water-borne transmission, which includes mosquitoes and amoebae as the potential host reservoirs of the bacteria in water environment. In vitro studies showed intracellular replication of F. tularensis within Acanthamoeba castellanii and Hartmanella vermiformis cells. While infection of amoeba by Legionella pneumophila has been shown to enhance infectivity of L. pneumophila the role of F. tularensis-infected protozoa in the pathogenesis of tularemia is not known. We used 6 h coculture of A. castellanii and F. novicida for investigation of the effect of inhaled amoeba on the pathogenesis of tularemia on in vivo model. Balb/c mice were infected intratracheally with F. novicida or with F. novicida-infected A. castellanii. Surprisingly, infection with F. novicida-infected A. castellanii did not lead to bronchopneumonia in Balb/c mice, and Francisella did not disseminate into the liver and spleen. Upon inhalation, F. novicida infects a variety of host cells, though neutrophils are the predominant cells early during infection in the lung infiltrates of pulmonary tularemia. The numbers of neutrophils in the lungs of Balb/c mice were significantly lower in the infection of mice with F. novicida-infected A. castellanii in comparison to group of mice infected only with F. novicida. These results demonstrate that following inoculation of mice with F. novicida-infected A. castellanii, mice did not develop tularemia. PMID:27242974

    Full Text Available OBJECTIVE: To assess intermediate-term outcome in children who have undergone orthotopic heart transplantation. METHODS: We carried out a longitudinal and prospective study between October '92 and June '99 comprising 20 patients with ages ranging from 12 days to 7 years (mean of 2.8 years. We employed a double immunosuppression protocol with cyclosporine and azathioprine and induction therapy with polyclonal antithymocyte serum. Survival and complications resulting from the immunosuppression protocol were analyzed. RESULTS:The double immunosuppression protocol and the induction therapy with polyclonal antithymocyte serum resulted in an actuarial survival curve of 90% and 78.2% at 1 and 6 years, respectively, with a mean follow-up period of 3.6 years. One patient died due to acute rejection 40 days after transplantation; another patient died 2 years after transplantation due to lymphoproliferative disorder; a third patient died because of primary failure of the graft; and a fourth patient died due to bronchopneumonia. The major complications were as follows: acute rejection, infection, nephrotoxicity, and systemic hypertension. The means of rejection and infection episodes per patient were 2.9 and 3.4, respectively. After one year of transplantation, a slight reduction in the creatinine clearance and systemic hypertension were observed in 7 (38.9% patients. CONCLUSION: Heart transplantation made life possible for those patients with complex congenital heart diseases and cardiomyopathies in refractory congestive heart failure constituting a therapeutical option for this group of patients in the terminal phase.

    Histophilus somni, a causative agent of the bovine respiratory disease complex, can also cause a variety of systemic disorders, including bronchopneumonia, myocarditis, pericarditis, arthritis, pleuritis, and infectious thrombotic meningoencephalitis. The purpose of this study was to determine if currently circulating strains differ from those of the 1980s by identifying genomic changes. Single nucleotide polymorphisms (SNPs) and insertion and deletion (INDEL) sites were examined by whole-genome sequencing in 12 samples, 6 old and 6 new. The 31 028 SNP/INDELs recorded were compared against the reference genome sequence of the pathogenic H. somni strain 2336. The distribution of about 75% of these SNPs within a specified gene differed between old and new isolates and did not follow any particular pattern. The other 25% clustered into 2 groups containing the same SNPs in various genes: group I included 5 old isolates and 1 new isolate; group II included 5 new isolates and 1 old isolate. For putative virulence genes there were more SNPs in group I compared with strain 2336, itself an older isolate, than in group II. Although only 25% of all the SNPs formed 2 clusters, the results suggest some genetic difference in various genes between old and new strains. PMID:26130851

  19. Respiratory syncytial virus infection of the lower respiratory tract: radiological findings in 108 children

    International Nuclear Information System (INIS)

    For years the typical appearance of respiratory syncytial virus (RSV)-induced infection of the lower respiratory tract has been discussed. All available studies have led to different results. The aim of this study was to control these results, with 108 children. The age range was 1 day to 10 years (median 7 months). Within 72 h of admission, all children developed an RSV infection of the lower respiratory tract. Chest X-rays (pa-view) of 55 children under, and 53 children over, the age of 6 months (10/53>24 months) were evaluated. The diagnosis of RSV and the chest X-ray were mostly done on the same day. The major radiological findings of the two age-groups were compared by Wilcoxon's unpaired rank sum test. Major radiological findings were: normal chest X-ray (30%), central pneumonia (32%) or peribronchitis (26%). There was no statistical significance between the age-groups. Other findings were emphysema (11%), pleural effusion (6%), lobar- or broncho-pneumonia (each 6%), atelectasis (5%) or pneumothorax in one case. Therefore, the most common radiological findings in RSV-induced infection of the lower respiratory tract, supported by our results (RSV infection without bacterial superinfection) are central pneumonia, peribronchitis or normal chest X-ray. Thus an age-group separation into under or over 6 months is no longer necessary. (orig.)

  20. Radiologic Review of an Outbreak of the Pandemic (H1N1) 2009 Virus Infection at a University Hospital in Seoul, Korea

    International Nuclear Information System (INIS)

    To assess the frequency of radiologic abnormalities and investigate the radiologic findings of patients with a pandemic (H1N1) 2009 virus infection at a University hospital in Seoul, Korea. In November 2009, 9,427 patients were tested for pandemic (H1N1) 2009 virus and 3,849 (41%) were positive. Among them, only 338 (9%) underwent chest radiographs and 13 (0.3%) received chest CT. Two radiologists retrospectively reviewed all the radiologic images. Among the 338 patients, 287 (85%) were normal and 51 (15%) showed abnormalities. The frequency of abnormalities was significantly higher in children (41/212=19%) than in adults (10/126=8%) (p = 0.005). Of them, 42 (82%) patients had airspace pneumonia, whereas the remaining patients showed a bronchopneumonia pattern. Unilateral (82%) involvement was more common than bilateral (18%) involvement. Among patients who received chest CT, 12 (92%) showed abnormalities, with bilateral (67%) and random (75%) involvement being more common. Ground-glass opacity (67%) and centrilobular nodules (58%) were the more common CT findings. Only a small number of patients were critically ill enough to undergo further radiologic evaluation as a result of pandemic (H1N1) 2009 virus infection, and most patients had normal chest radiographs. Unilateral airspace pneumonia was the most common abnormality in patients infected with pandemic (H1N1) 2009 virus.

  1. Ground-glass opacity in diffuse lung diseases: high-resolution computed tomography-pathology correlation

    International Nuclear Information System (INIS)

    Ground-glass opacity is a finding frequently seen in high-resolution computed tomography examinations of the chest and is characterized by hazy increased attenuation of lung, however without blurring of bronchial and vascular margins. Due to its un specificity, association with other radiological, clinical and pathological findings must be considered for an accurate diagnostic interpretation. In this paper were reviewed 62 computed tomography examinations of patients with diffuse pulmonary diseases of 14 different etiologies in which ground-glass opacity was the only or the most remarkable finding, and correlated this findings with pathology abnormalities seen on specimens obtained from biopsies or necropsies. In pneumocystosis, ground-glass opacities correlated histologically with alveolar occupation by a foaming material containing parasites, in bronchiole alveolar cell carcinoma with thickening of the alveolar septa and occupation of the lumen by mucus and tumoral cells, in paracoccidioidomycosis with thickening of the alveolar septa, areas of fibrosis and alveolar bronchopneumonia exudate, in sarcoidosis with fibrosis or clustering of granulomas and in idiopathic pulmonary fibrosis with alveolar septa thickening due to fibrosis. Alveolar occupation by blood was found in cases of leptospirosis, idiopathic hemo siderosis, metastatic kidney tumor and invasive aspergillosis whereas oily vacuole were seen in lipoid pneumonia, proteinaceous and lipo proteinaceous material in silico proteinosis and pulmonary alveolar proteinosis, and edematous fluid in cardiac failure.

    Capturing disease trends among different species has indisputable value to both veterinary clinicians and zoo managers for improving the welfare and management of zoo species. The causes of mortality for eight species of gazelle (addra gazelle, Nanger dama; dorcas gazelle, Gazella dorcas; Grant's gazelle, Nanger granti; sand gazelle, Gazella leptoceros; Saudi goitered gazelle, Gazella subgutturosa; Soemmerring's gazelle, Nanger soemmerringii; Thomson's gazelle, Eudorcas thomsonii; and Speke's gazelle, Gazella spekei) are presented from an 18-yr period (1996 2014). The leading cause of mortality for all species was trauma, followed by bronchopneumonia, and failure to thrive/maternal neglect. Nephritis and rumenitis/abomasitis/enteritis were common ancillary lesions across all species. On average, female gazelle lived twice as long as male gazelle, with an average overall adult survival time of 9.3 yr. Dorcas, Thomson's and addra gazelle females had the longest average survival time (10-13 yr). Calves up to 6 mo of age died most frequently from failure of passive transfer or maternal neglect. Thyroid carcinoma was frequently identified in Thomson's gazelle. Sand and Speke's gazelle frequently died from systemic amyloidosis, and Saudi goitered gazelle were more likely to have renal amyloidosis. Hematuria syndrome was the second most common cause of death in Grant's gazelle. The majority of lesions identified in this study that cause or contribute to mortality are preventable with appropriate management. Knowledge of disease trends in captive gazelle populations can help guide veterinary care, management decisions, and collection management planning. PMID:27010271

    Background: The natural history and consequences of severe H1N1 influenza infection among cancer patients are not yet fully characterized. We describe eight cases of H1N1 infection in cancer patients admitted to the intensive care unit of a referral cancer center. Patients and methods: Clinical data from all patients admitted with acute respiratory failure due to novel viral H1N1 infection were reviewed. Lung tissue was submitted for viral and bacteriological analyses by real-time RT-PCR, and autopsy was conducted on all patients who died. Results: Eight patients were admitted, with ages ranging from 55 to 65 years old. There were five patients with solid organ tumors (62.5%) and three with hematological malignancies (37.5%). Five patients required mechanical ventilation and all died. Four patients had bacterial bronchopneumonia. All deaths occurred due to multiple organ failure. A milder form of lung disease was present in the three cases who survived. Lung tissue analysis was performed in all patients and showed diffuse alveolar damage in most patients. Other lung findings were necrotizing bronchiolitis or extensive hemorrhage. Conclusions: H1N1 viral infection in patients with cancer can cause severe illness, resulting in acute respiratory distress syndrome and death. More data are needed to identify predictors of unfavorable evolution in these patients. PMID:20511340

    Full Text Available Sulphur mustard is a chemical warfare agent, which was largelyused during the World War One and in Iraq-Iran conflict. It mayalso be used as a chemical terrorism agent. Therefore, medicalprofessions should have sufficient knowledge and be preparedfor medical intervention of any such chemical attack.Sulphur mustard exerts direct toxic effects on the eyes, skin,and respiratory tract, with subsequent systemic actions on thenervous, immunologic, hematologic, digestive, and reproductivesystems. It is an alkylating agent that affects DNA synthesis andthus, delayed complications have been considered since theWorld War One. Cases of malignancies in the target organs particularlyin hematopoietic, respiratory, and digestive systemswere reported. Common delayed respiratory complications includechronic bronchitis, bronchiectasis, frequent bronchopneumonia,and pulmonary fibrosis, all of which tend to deterioratewith time. Severe dry skin, delayed keratitis, and reduction ofnatural killer cells with subsequent increased risk of infectionsand malignancies are also among the most distressing long-termconsequences of sulphur mustard intoxication. However, despiteextensive research that has been conducted on Iranian veteransduring the past decades, major gaps continue to remain in thesulphur mustard literature. Immunological and neurological dysfunctionsand the relationship between exposure to sulphur mustardand mutagenicity, carcinogenicity, and teratogenicity areimportant fields that require further studies, particularly on Iranianveterans with chronic health problems caused by sulphurmustard poisoning. There is also a paucity of information on themedical management of acute and delayed toxic effects of sulphurmustard poisoning, a subject that greatly challenges themedical professions.

    Cryptococcosis has been reported in marine mammals in the northeastern Pacific with increasing frequency in the last 15 yr. Although a variety of cetaceans have been diagnosed with cryptococcosis, Cryptococcus gattii has not been reported in pinnipeds. We document C. gattii VGIIa in a harbor seal ( Phoca vitulina ) pup and in an unrelated adult. Both animals were presented to Vancouver Aquarium's Marine Mammal Rescue Centre (VAMMRC) with generalized weakness, dehydration, respiratory compromise, minimally responsive mentation, and suboptimal body condition. Necropsy and histopathology findings were consistent in both animals and featured generalized lymphadenopathy, bronchopneumonia, and meningoencephalitis with intralesional yeast and fungemia. Cryptococcal serum antigen titers were ≥1,024 in both animals. Fungal culture of lung and lymph nodes confirmed C. gattii . Exposure was likely via inhalation prior to presentation to VAMMRC, and C. gattii infection was the proximate cause of death. This report expands the range of susceptible host species as C. gattii continues to emerge as a pathogen of concern in marine mammals in the northeastern Pacific. PMID:27243332

    We report a case of acute hemorrhagic leukoencephalomyelitis in a man with viral myocarditis. A 48-year-old previously healthy male was found dead in his locked apartment. At autopsy he was found to be malnourished, and his lungs showed gross evidence of bilateral pneumonia with abscess formation and bullous emphysema. Multiple petechial hemorrhages were observed in the brain and mainly involved white matter in the cerebral hemispheres including the corpus callosum and internal capsule, as well as the cerebellum, brainstem, and spinal cord. Microscopy of the brain and spinal cord revealed perivenular hemorrhages, central microthrombi in venules with fibrin exudation into the subcortical white matter, and early perivenular demyelination associated with scanty mixed cellular infiltrates. Other microscopic features included widespread diffuse viral myocarditis, extensive suppurative bronchopneumonia, and chronic bronchitis. This case illustrates the death of a man with a rare fatal disease associated with two other potentially lethal diseases. The case also illustrates the importance of a holistic approach when determining the cause of death, especially when there are competing causes of death. PMID:26148811

    When abuse, maltreatment and neglect are suspected, a proper physical examination is essential. This is even more important at autopsy, when there is no possibility to gain information from the alleged victim and where the forensic pathologist has to link the evidenced signs or sequalae of abuse with the possible manner and cause of death. This case report presents the results and conclusions of the medico-legal autopsy of a 30-year-old woman found dead in her fiancé's home. The conditions and material evidence found on scene aroused doubts on the cause and manner of death. Dermatological signs found on the corpse (abrasions, contusions and decubitus ulcers) suggested a history of domestic abuse and neglect that was further confirmed by a detailed macroscopic and microscopic examination of the body. An insight into the woman's medical history further implied the possibility of long-term domestic violence. The forensic pathologist reported bronchopneumonia as the main cause of death, provoked by the combined effect of malnourishment, deliberated immobilization and neglected decubitus ulcers. This case is uncommon as it presents the homicide of a young woman caused by a prolonged abusive behaviour associated with complete neglect of her aggravating health conditions and provoked injuries.

    INTRODUCTION. Bronchopneumonia is a frequent complication in the first days after a cerebrovascular disease and is linked with a higher rate of mortality. It occurs in patients with an altered level of consciousness or tussigenic reflex, and could be prevented with an early dysphagia rehabilitation programme. AIMS. To review the scientific literature on the treatment and rehabilitation of patients with dysphagia after suffering a stroke, published between 2002 and 2012. DEVELOPMENT. A search conducted in the PubMed, Cochrane, PEDro, CINAHL and ENFISPO databases yielded 15 papers that fulfilled eligibility criteria and the initial aims of the study, providing information about 3,212 patients. The different protocols and techniques for re-education in dysphagia are described and include compensatory strategies, orofacial regulation therapy, music therapy, sensory stimulation, lip muscle, tongue, pharynx, larynx and respiratory tract training, Mendelsohn manoeuvre, neuromuscular electrical stimulation, repetitive transcranial magnetic stimulation and acupuncture. CONCLUSIONS. The studies examined in this research claim that the treatment of dysphagia following a stroke can improve the function of deglutition (coordination, speed, volume), quality of life and people's social relationships. Further work needs to be carried out to establish or define what kind of therapies, techniques, exercises or manoeuvres are the most effective in dysphagia. Generally agreed treatment or rehabilitation protocols also need to be drawn up within units that address stroke in an integrated manner. PMID:24610693

    In 2007, disease related mortality occurred in one African wild dog (Lycaon pictus) pack close to the north-eastern boundary of the Serengeti National Park, Tanzania. Histopathological examination of tissues from six animals revealed that the main pathologic changes comprised interstitial pneumonia and suppurative to necrotizing bronchopneumonia. Respiratory epithelial cells contained numerous eosinophilic intracytoplasmic inclusion bodies and multiple syncytial cells were found throughout the parenchymal tissue, both reacting clearly positive with antibodies against canine distemper virus (CDV) antigen. Phylogenetic analysis based on a 388 nucleotide (nt) fragment of the CDV phosphoprotein (P) gene revealed that the pack was infected with a CDV variant most closely related to Tanzanian variants, including those obtained in 1994 during a CDV epidemic in the Serengeti National Park and from captive African wild dogs in the Mkomazi Game Reserve in 2000. Phylogenetic analysis of a 335-nt fragment of the fusion (F) gene confirmed that the pack in 2007 was infected with a variant most closely related to one variant from 1994 during the epidemic in the Serengeti National Park from which a comparable fragment is available. Screening of tissue samples for concurrent infections revealed evidence of canine parvovirus, Streptococcus equi subsp. ruminatorum and Hepatozoon sp. No evidence of infection with Babesia sp. or rabies virus was found. Possible implications of concurrent infections are discussed. This is the first molecular characterisation of CDV in free-ranging African wild dogs and only the third confirmed case of fatal CDV infection in a free-ranging pack. PMID:20684868

  10. Chronic health effects of sulphur mustard exposure with special reference to Iranian veterans

    Full Text Available The widespread use of sulphur mustard (SM as an incapacitating chemical warfare agent in the past century has proved its long-lasting toxic effects. It may also be used as a chemical terrorist agent. Therefore, all health professionals should have sufficient knowledge and be prepared for any such chemical attack. SM exerts direct toxic effects on the eyes, skin, and respiratory tissue, with subsequent systemic action on the nervous, immunological, haematological, digestive, and reproductive systems. SM is an alkylating agent that affects DNA synthesis, and, thus, delayed complications have been seen since the First World War. Cases of malignancies in the target organs, particularly in haematopoietic, respiratory, and digestive systems, have been reported. Important delayed respiratory complications include chronic bronchitis, bronchiectasis, frequent bronchopneumonia, and pulmonary fibrosis, all of which tend to deteriorate with time. Severe dry skin, delayed keratitis, and reduction of natural killer cells with subsequent increased risk of infections and malignancies are also among the most distressing long-term consequences of SM intoxication. However, despite a lot of research over the past decades on Iranian veterans, there are still major gaps in the SM literature. Immunological and neurological dysfunction, as well as the relationship between SM exposure and mutagenicity, carcinogenicity, and teratogenicity are important fields that require further studies, particularly on Iranian veterans with chronic health effects of SM poisoning. There is also a paucity of information on the medical management of acute and delayed toxic effects of SM poisoning—a subject that greatly challenges health care specialists.

  11. Radiosensitivity and clinical symptoms of the acute radiation syndrome in calves and young cattle

    International Nuclear Information System (INIS)

    38 calves, aged 2.5 to 4 months were exposed to bilateral whole-body X-ray treatment. Incident doses were between 1.80 Gy and 2.80 Gy. An incident dose in excess of 3.0 Gy has to be considered as Ldsub(100/30) for calves in the above age group, while incident doses between 2.2 Gy and 2.5 Gy are LDsub(50/30) and 1.8 Gy being LDsub(0/30). The clinical symptoms of the acute radiation syndrome were clearly phased in response to doses between 2.0 Gy and 4.0 Gy (primary, latency, main reaction, and recovery periods). Following the above doses, the death of the animals, occurred between the middle of the third and end of the fourth week after irradiation. The clinical symptoms are described in detail. Only the symptoms in the main reaction phase depend unambiguously on dosage. There were more frequent febrile rectal temperatures, higher incidence of bronchopneumonia, and disturbances of movement. The acute clinical symptoms gradually faded away in the phase of transition to recovery towards the end of the fourth week after irradiation. (author)

  12. Clinical study of infectious diseases on aged A-bomb survivors in Hiroshima Welfare Home for aged A-bomb survivors

    International Nuclear Information System (INIS)

    Infections, especially urinary passage and respiratory infections of aged A-bomb survivers under special protective care was examined. Urinary passage infections have recently shown an increasing tendency. These infections are related to the factors such as their basic diseases and wearing napkins rather than a severe degree of protective care. In the case of respiratory infection, diseases such as influenza are observed rather in patients who can walk, but they tend to be aggravated in bedridden patients. It cannot be said that more urinary passage infections are observed in A-bomb survivers than non A-bomb survivers. Both urinary passage infection and respiratory infection tend to recur repeatedly. Aged A-bomb survivers show no significant difference of acquired immunity from that of non A-bomb survivers group. However, a maintenance of neutralizing antibody by vaccination of influenza in the former is worse than in the latter. Bedridden patients show a higher rate of infection to potential urinary passage diseases than patients who can walk, irrespective of sex. Moreover, bedridden patients have a large number of bacteria, but other significant host reaction couldn't be observed. In bedridden patients with potential urinary passage infection, a variety of bacteria, most of which are bacteria resistant to rutinely used broad spectrum antibiotics, is detected. As a main disease or a direct cause of death, pyelonephritis in women and bronchopneumonia are often observed. (Iwagami, H.)

    Lung involvement in Crohn's disease is not well characterized. We reviewed our experience with 11 lung biopsies (seven wedge and four transbronchial) from patients with Crohn's disease to study this association further. Negative cultures, special stains for organisms Gomori-methenamine-silver [GMS], acid fast), and polymerase chain reaction for (four cases) were required for inclusion. The group included five women and six men with a mean age of 47 years (range 13-84 years). A diagnosis of Crohn's disease preceded the lung disease in nine patients. In two patients the diagnosis of Crohn's disease followed the diagnosis of their pulmonary disease 1 and 15 months later. Radiologically, eight patients had diffuse infiltrates, two had bilateral nodular infiltrates, and one had a mass. Chronic bronchiolitis with nonnecrotizing granulomatous inflammation was present in four patients, one of whom was taking mesalamine. Two patients had an acute bronchiolitis associated with a neutrophil-rich bronchopneumonia with suppuration and vague granulomatous features. One patient on mesalamine had cellular interstitial pneumonia with rare giant cells. Four patients demonstrated organizing pneumonia with focal granulomatous features, two of whom were taking mesalamine, and one of these two responded to infliximab (anti-tumor necrosis factor) monoclonal antibody therapy. Noninfectious pulmonary disease in patients with Crohn's disease has variable histologic appearances, including granulomatous inflammation and airway-centered disease resembling that seen in patients with ulcerative colitis. Drugs may contribute to pulmonary disease in some patients. PMID:12548168

    There are divergent views about the harm that pectus excavatum and related chest deformities does to the respiratory and heart function. The indications for surgery and the optimal age for surgical intervention are debatable. In this study 37 operated and 38 nonoperated cases of about the same severity have been followed for more than ten years and examined after the age of 18 years. The examination included socio-economic, cosmetic and cardio-pulmonary function aspects. It could be shown that from the psychological aspect there were no significant differences between the operated and the non-operated cases. The tendency to contract bronchopneumonia is not influenced by operation. The physical working capacity was the same in the two groups. The operated cases have slightly lower pulmonary function values that the non-operated in spite of the fact that the non-operated group at the time of follow-up included the more seveee cases. Age at operation did not seem to be of any importance for the long-term results. The lower pulmonary function capacity in the operated cases is thought to be attributed to a restriction secondary to the operation. There are also indications that pectus excavatum tends to become less pronounced with increasing age. The study supports a restrictive attitude towards surgery. PMID:1058627

    2012-12-01

    A novel herpesvirus infection in nine Bourke's parrots (Neopsephotus bourkii, formerly Neophema bourkii) housed in an outdoor aviary comprised of multiple species of birds was diagnosed based on histopathology, electron microscopy and polymerase chain reaction (PCR). Clinical signs in the parrots included anorexia, ruffled feathers, depression, loss of weight and respiratory distress. The most common gross lesions were moderately congested and oedematous lungs and a mild fibrinous exudate in the air sacs and lumen of the trachea. Histological examination revealed mild to severe bronchopneumonia and airsacculitis with syncytial cells containing eosinophilic intranuclear inclusion bodies in most birds. Other less frequent changes included tracheitis, syringitis, sinusitis, rhinitis, otitis media and conjunctivitis. Attempts to culture the virus in chicken embryos and chicken embryo liver cells were unsuccessful. Examination by transmission electron microscopy of syncytial cells from the lungs of two birds revealed intranuclear virus particles typical of the family Herpesviridae. DNA from a novel herpesvirus was amplified from lung tissue by PCR using degenerate primers derived from conserved avian herpesvirus sequences. The virus belongs in the genus Iltovirus of the Alphaherpesvirinae subfamily. It is not closely related to Psittacid herpesvirus 1 that causes Pacheco's disease but does group phylogenetically with a clade of herpesviruses that cause respiratory disease in a number of avian species. The proposed name for this herpesvirus is Psittacid herpesvirus 3. PMID:23237365

  17. Hyperlucent lung

    International Nuclear Information System (INIS)

    Unilateral hyperlucent lung is also known as Swyer-James Syndrome, Macleod Syndrome or lobular or unilateral emphysema. It is an uncommon disease characterized by lung or unilateral lobe hiperlucency associated to an air trapping upon expiration. As regards to etiology, this syndrome is considered to be an acquired disease that appears secondary to respiratory infections during the early years of life, probably bronchiolitis and/ or viral pneumonia. The clinical presentation varies among patients. Some of them are asymptomatic, others present a history of recurrent episodes of pulmonary infections from early years of life or present effort dyspnea. The diagnosis is usually made accidentally by a chest radiograph in a child with history of respiratory infections or in an adult during a routine chest x- ray in an asymptomatic person. It is important to differentiate this syndrome from other causes of unilateral pulmonary hiperlucency on conventional chest x-rays. Few cases of Swyer-James Syndrome in children have been reported, it is presented the clinical case of a patient who had a parainfluenza 3 bronchopneumonia when he was a month and eighteen days of age. The differential diagnosis of this syndrome should be done with other thoracic entities that diminish the radiological pulmonary unilateral density. A case of a child who is the bearer of hyperlucent lung is described. (author)

    The sudden death of three calves, one diarrheic calf, and one aborted fetus from four farms in southern Brazil was investigated. Two Histophilus somni-associated syndromes were identified: systemic histophilosis (n = 4) and abortion (n = 1). The principal pathological findings included vasculitis, meningoencephalitis with thrombosis, necrotizing myocarditis, renal infarctions, hepatic abscesses, and bronchopneumonia. PCR assays were used to amplify specific amplicons of the ovine herpesvirus 2, bovine herpesvirus 1 and -5, Listeria monocytogenes, H. somni, and pestivirus; bovine group A rotavirus (BoRV-A) and bovine coronavirus (BCoV) were investigated in calves with diarrhea. H. somni DNA was amplified in tissues from all calves and the brain of the aborted fetus with pathological alterations consistent with histophilosis. All other PCR assays were negative; BoRV-A and BCoV were not identified. These findings confirm the participation of H. somni in the pathological alterations observed in this study and represent the first description of histophilosis in cattle from Brazil. PMID:23526124

    To assess the frequency of radiologic abnormalities and investigate the radiologic findings of patients with a pandemic (H1N1) 2009 virus infection at a University hospital in Seoul, Korea. In November 2009, 9,427 patients were tested for pandemic (H1N1) 2009 virus and 3,849 (41%) were positive. Among them, only 338 (9%) underwent chest radiographs and 13 (0.3%) received chest CT. Two radiologists retrospectively reviewed all the radiologic images. Among the 338 patients, 287 (85%) were normal and 51 (15%) showed abnormalities. The frequency of abnormalities was significantly higher in children (41/212=19%) than in adults (10/126=8%) (p = 0.005). Of them, 42 (82%) patients had airspace pneumonia, whereas the remaining patients showed a bronchopneumonia pattern. Unilateral (82%) involvement was more common than bilateral (18%) involvement. Among patients who received chest CT, 12 (92%) showed abnormalities, with bilateral (67%) and random (75%) involvement being more common. Ground-glass opacity (67%) and centrilobular nodules (58%) were the more common CT findings. Only a small number of patients were critically ill enough to undergo further radiologic evaluation as a result of pandemic (H1N1) 2009 virus infection, and most patients had normal chest radiographs. Unilateral airspace pneumonia was the most common abnormality in patients infected with pandemic (H1N1) 2009 virus.

  1. Radiologic and clinical findings of mycoplasma pneumonia in children

    International Nuclear Information System (INIS)

    Mycoplasma Pneumonia is a cause of primary atypical pneumonia, but it is asymptomatic mostly or may cause of only mild symptoms. School-aged children experienced high attack rate and manifestation if 'unusual pneumonia' are noted. So authors reviewed clinical and radiological features of 110 cases of serologically proven Mycoplasma pneumonia in hospitalized children between November 1984 and January 1987 retrospectively. The results were as follows ; 1. The sex distribution was 57:53 (1.1:1) in male to female ratio and 47% of them were 5 though 8 years old of age with peak incidence between 5 and 6 years old of age. 2. The symptoms were cough, fever, and sore throat in descending order of frequency and mean symptom duration before admission was 8.1 day. The prevalent season was earlier winter. 3. The radiologic findings were air-space consolidation with lobar, segmental distribution in 68%, interstitial infiltration in 12%, bronchopneumonia in 12%, chronic bronchitis pattern in 3.6%, normal in 4.5%, hilar LN enlargement in 37%, pleural effusion in 12%. 4. Radiologic resolution period was usually 10 days around (4-25 days) and after complete recovery, scarring change or calcification was not seen. 5. Extrapulmonary manifestations were uncommon but hepatitis, hematuria, skin rash, gastroenteritis, myocarditis, otitis media occurred. 6. With administration of tetracyclin and erythromycin, clinical and radiologic responses were promptly seen

  2. Mycoplasma pneumoniae pneumonia: CT features in 16 patients

    The objective of this study was to assess the computed tomography (CT) features of Mycoplasma pneumoniae pneumonia. We retrospectively reviewed CT findings of 16 patients (M:F=9:7, age range 1-74 years, median 9 years) with serologically proven Mycoplasma pneumoniae pneumonia and with chest CT scan available. Two distinctive patterns of CT features of M. pneumoniae pneumonia were noted between the paediatric (age <18 years) and the adult (age ≥18 years) groups. The pediatric group (n=11) showed lobar or segmental consolidation (100%) with frequent pleural effusion (82%) and regional lymphadenopathy (82%) and mild volume decrease of the involved lobe (73%), while four of the five adult patients showed diffuse and/or multifocal, centrilobular or peribronchovascular areas of ground-glass attenuation (80%) with a lobular distribution, and frequent thickening of interlobular septa (60%) and the bronchial walls (40%) were also detected at high-resolution CT. The CT finding of a lobar or segmental consolidation with a parapneumonic effusion seen in our children with M. pneumoniae pneumonia was similar to that of bacterial lobar pneumonia. In contrast, the CT findings noted in our adult patients consisted of a mixture of a bacterial bronchopneumonia pattern and a viral interstitial pneumonia pattern. (orig.)

    Mycoplasma bovis is a major pathogen affecting cattle causing bronchopneumonia, mastitis, and other disorders. Only autogenous vaccines made specifically for individual farms are available in parts of Europe and the United States. A novel experimental vaccine composed of a field M. bovis isolate combined with saponin and Emulsigen(®) adjuvants was evaluated. Eighteen 3-4 week old calves were placed in three equal groups: vaccinated (Vac), positive control (PC) and negative control (NC). The Vac calves were subcutaneously injected with 8ml of the vaccine; the PC and NC calves received phosphate buffered saline (PBS). Three weeks later the Vac and PC calves were challenged with a virulent M. bovis strain, the NC group received PBS. Throughout the study clinical observations, microbiology and immunological tests were carried out. Three weeks post challenge two calves from each group were euthanased for necropsy and histopathological examination. The vaccine effectively stimulated the humoral immune response, with high titres of anti-M. bovis specific antibodies and total Ig concentration. This vaccine also intensified the IgA response. A clinically protective effect of the vaccine was demonstrated as it also reduced the gross pathological lung lesions and nasal shedding of M. bovis. PMID:27156637

    Porcine reproductive and respiratory syndrome virus (PRRSV) is endemic in most parts of Asia, where genotype I and II strains of diverse virulence may coexist. This study evaluated the outcome of infection with a highly virulent Asian genotype II PRRSV isolate in piglets vaccinated with a genotype I vaccine. Twenty-one 3-week-old piglets were divided in three groups: Pigs in group V (n=8) were vaccinated with an attenuated genotype I commercial PRRSV vaccine, while pigs in group U (n=8) and a control group (group C; n=5) were unvaccinated; 6 weeks later, pigs in groups V and U were challenged intranasally with a highly virulent strain of genotype II PRRSV (1×10(5) 50% tissue culture infectious doses/mL), while pigs in group C received a placebo. Over a period of 21 days after challenge, vaccinated pigs had significantly lower mortality (0/8 versus 2/8), fewer days of fever, a lower frequency of catarrhal bronchopneumonia, higher weight gains (13.4 versus 6.6 kg) and lower levels of viraemia compared to unvaccinated challenged pigs. Immunisation with a genotype I attenuated PRRSV vaccine provided partial protection against challenge with a highly virulent genotype II strain. PMID:22264642

    A novel avipoxvirus caused diphtheritic lesions in the oesophagus of five and in the bronchioli of four Magellanic penguins (Spheniscus magellanicus) and also cutaneous lesions in eight Magellanic penguins housed in outdoor enclosures in a Rehabilitation Centre at Florianópolis, Santa Catarina State, Brazil. At the same time, another avipoxvirus strain caused cutaneous lesions in three Magellanic penguins at a geographically distinct Rehabilitation Centre localized at Vila Velha, Espírito Santo State, Brazil. Diagnosis was based on clinical signs, histopathology and use of the polymerase chain reaction (PCR). Clinical signs in the penguins included cutaneous papules and nodules around eyelids and beaks, depression and restriction in weight gain. The most common gross lesions were severely congested and haemorrhagic lungs, splenomegaly and cardiomegaly. Histological examination revealed Bollinger inclusion bodies in cutaneous lesions, mild to severe bronchopneumonia, moderate periportal lymphocytic hepatitis, splenic lymphopenia and lymphocytolysis. Other frequent findings included necrotizing splenitis, enteritis, oesophagitis, dermatitis and airsacculitis. Cytoplasmic inclusion bodies were seen within oesophageal epithelial cells in five birds and in epithelial cells of the bronchioli in four penguins. DNA from all samples was amplified from skin tissue by PCR using P4b-targeting primers already described in the literature for avipoxvirus. The sequences showed two different virus strains belonging to the genus Avipoxvirus of the Chordopoxvirinae subfamily, one being divergent from the penguinpox and avipoxviruses already described in Magellanic penguins in Patagonia, but segregating within a clade of canarypox-like viruses implicated in diphtheritic and respiratory disease.

    In this retrospective study, 218 pig lung tissue samples were analyzed to examine a possible association between Pneumocystis spp. using in situ hybridization, Bordetella bronchiseptica (B.b.) using immunohistochemistry (IHC), Mycoplasma hyopneumoniae (M.h.) by quantitative PCR, and Pasteurella multocida (P.m.; IHC). Compared to the bacterial agents (B.b., 5%; M.h., 30%; P.m., 23%), Pneumocystis occurred with a higher prevalence (51%). Co-infections with two or three pathogens were present in 28% of the examined cases. Those of Pneumocystis and M.h. were most commonly seen, followed by Pneumocystis and P.m. and M.h. and P.m. Histologically, interstitial pneumonia was found in both the Pneumocystis positive lungs and lungs with a mild M.h. infection. The B.b. and P.m. positive lungs were mainly associated with suppurative bronchopneumonia and severe M.h. cases with fibrinous or fibrino-haemorrhagic pneumonia. In suckling piglets, the number of samples positive for Pneumocystis predominated, whereas samples from fattening pigs were mainly positive for bacteria or Pneumocystis and bacteria. PMID:26654847

    Ground-glass opacity is a finding frequently seen in high-resolution computed tomography examinations of the chest and is characterized by hazy increased attenuation of lung, however without blurring of bronchial and vascular margins. Due to its un specificity, association with other radiological, clinical and pathological findings must be considered for an accurate diagnostic interpretation. In this paper were reviewed 62 computed tomography examinations of patients with diffuse pulmonary diseases of 14 different etiologies in which ground-glass opacity was the only or the most remarkable finding, and correlated this findings with pathology abnormalities seen on specimens obtained from biopsies or necropsies. In pneumocystosis, ground-glass opacities correlated histologically with alveolar occupation by a foaming material containing parasites, in bronchiole alveolar cell carcinoma with thickening of the alveolar septa and occupation of the lumen by mucus and tumoral cells, in paracoccidioidomycosis with thickening of the alveolar septa, areas of fibrosis and alveolar bronchopneumonia exudate, in sarcoidosis with fibrosis or clustering of granulomas and in idiopathic pulmonary fibrosis with alveolar septa thickening due to fibrosis. Alveolar occupation by blood was found in cases of leptospirosis, idiopathic hemo siderosis, metastatic kidney tumor and invasive aspergillosis whereas oily vacuole were seen in lipoid pneumonia, proteinaceous and lipo proteinaceous material in silico proteinosis and pulmonary alveolar proteinosis, and edematous fluid in cardiac failure.

    Objective: To describe the representation of pertussis diagnosis in children. Methods: A retrospective observational study was performed on pediatric pertussis and pertussis-like syndrome registry for children <14 years of age documented from October 2008 to December 2014 in Hasan Sadikin Hospital, Indonesia. Demographic data, signs and symptoms at presentation, case definition (probable, confirmed), possible pertussis contact, pertussis vaccination status, results of Bordetella pertussis (B. pertussis) culture, complications, and outcome were recorded. Results:Sixty-one probable and two confirmed pertussis were documented. Male and female ratio was 1:1, mostly presented with shortness of breath, 24 (38%) subjects had posttussive vomiting, 10 (16%) had whooping-cough. Ten patients (16%) were reported to have adult possible pertussis contact. Only 2 infants had previous pertussis vaccination. All subjects presented in the second week of illness were all diagnosed as bronchopneumonia but two. The mean age was 6 months, ranging from 0−50 months. One subject required mechanical ventilation. B. pertussis culture was performed only in 35 (56%) subjects but positive only in two. There were no fatal cases, 55 (87%) including the subject who need mechanical ventilation had good outcome. Conclusions: Mostly patients were admitted on paroxysmal phase when no more active B. pertussis could be found from nasopharyngeal secret. A rigorous history taking particularly excessive cough, posttussive vomitting, and pertussis vaccination status need to be taken into account.

    Full Text Available Eventration of diaphragm (ED refers to an abnormally high position of part or all of the diaphragm, but intact diaphragm, usually associated with a marked decrease in muscle fibers and a membranous appearance of the abnormal area with only the peripheral thoracic attachments showing normal muscle. Etiologically ED is congenital or acquired. Congenital diaphragmatic abnormalities occur in 1 per 2000 to 4000 birth, which 7% is diaphragmatic eventration. Most children with ED are asymptomatic when incidentally first seen, will not need theraphy. Those with symptoms develop acute respiratory distress, feeding difficulties, and recurrent pneumonitis. If the patient need assissted ventilation or cannot be weaned off the ventilator, she or he should be plicated. Failure to achieve extubation within a week of plication is an ominous prognostic sign. We reported a case of one month and four days old girl who was dispnea, feeding difficulty and bronchopneumonia caused by right ED with acquired etiology. Plication was done to repaired the symptom. But unfortunately this was not succeded because there was complication of postoperative treatment.

  11. Identification of titanium in human tissues: probable role in pathologic processes

    International Nuclear Information System (INIS)

    Six cases of titanium dioxide exposure involving lung, skin, and synovium are described, with a review of the literature. The patients, four men and two women, were between the ages of 22 and 65 years. The pulmonary changes were characterized by fibrosis and numerous macrophages with abundant deposition of a black pigment. Adjacent areas of bronchopneumonia were also observed. In the skin a severe necrotizing lesion involving the subcutaneous tissue with extension to the muscle was observed in one case and a nonspecific inflammatory response was observed in another; both cases showed abundant black pigment deposition. Electron microscopy and energy dispersive x-ray analysis demonstrated the presence of large quantities of titanium in the pigment granules. There may be a combination of black pigment deposition and fibrosis, necrosis, or a xanthomatous or granulomatous reaction, that, together with negative results on special staining and culture studies for organisms, should raise the suspicion of titanium-associated injury and prompt the study of the affected tissues by x-ray analysis for positive identification

    Full Text Available Introduction: Up to 40 weeks of postconceptional age, the kangaroo mother program at the Hospital Universitario del Valle has proved to be a safe alternative for premature babies’ management with a low birth weight. Objectives: To evaluate the physical growth and morbidity in children followed since 40 weeks up to 1 year in the program. Material and methods: A cohort study was performed in newborn infants admitted to the kangaroo mother program in the newborn unit at the Hospital Universitario del Valle, Cali, Colombia, with birth weight lower than 2000 g, from 40 weeks postconceptional age up to one year age, between August 2002 and July 2006. Information was collected about maternal age and morbidity, prenatal control, type of birth, gender, birth weight, gestational age, breastfeeding, thick motor development, physical growth, morbidity, readmissions, mortality and tests results. Results: A total of 390 infants were admitted to the program, with a 61% of captation. 65% of theirs mothers did not have prenatal control. Before completing the 40 weeks, 5.3% were readmitted due to anaemia and apnoea. After 40 weeks, 13% were readmitted by bronchopneumonia and acute diarrhoea. Most of them were allocated in the reference percentiles for weight and size. Size had a better growth than weight. The cumulated low weight incidence for age at 13 months was 22%. Conclusions: To increase the coverage of prenatal control program and to watch that the children receive prescribed iron and formulated folic acid.

    Rhodococcus equi is a soil bacterium and, like Mycobacterium tuberculosis, a member of the mycolata. Through possession of a virulence plasmid, it has the ability to infect the alveolar macrophages of foals, resulting in pyogranulomatous bronchopneumonia. The virulence plasmid has an orphan two-component system (TCS) regulatory gene, orf8, mutation of which completely attenuates virulence. This study attempted to find the cognate sensor kinase (SK) of orf8. Annotation of the R. equi strain 103 genome identified 23 TCSs encoded on the chromosome, which were used in a DNA microarray to compare TCS gene transcription in murine macrophage-like cells to growth in vitro. This identified six SKs as significantly up-regulated during growth in macrophages. Mutants of these SKs were constructed and their ability to persist in macrophages was determined with one SK, MprB, found to be required for intracellular survival. The attenuation of the mprB- mutant, and its complementation, was confirmed in a mouse virulence assay. In silico analysis of the R. equi genome sequence identified an MprA binding box motif homologous to that of M. tuberculosis, on mprA, pepD, sigB and sigE. The results of this study also show that R. equi responds to the macrophage environment differently from M. tuberculosis. MprB is the first SK identified as required for R. equi virulence and intracellular survival. PMID:20637548

    The role of meconium in the respiratory system was studied in newborns, who died from various causes (250 up to 3000 g of weight). We monitored tracheal rings response to dopamine, serotonin and ethanol in different concentrations (dopamine: 0,05 mg/ml, 0,5 mg/ml, 5 mg/ml; serotonin (5-HT): 10-4, 10-3, 10-2, 10-1 mol/dm3; ethanol: 0,02 ml, 0,5 ml, 1,0 ml; 96%). Tracheal smooth musculature tonus (TSM) was examined in 48 tracheal preparations taken after the newborn exitus due to different reasons. Based on functional researche of isolated preparations of tracheas, it may be concluded that: aspiration of meconium has not changed the response of TSM to dopamine, serotonin and ethanol (p>0,1) in comparison with the control group, which have died due to different lung inflammatory processes (e.g. pneumonia, bronchopneumonia, atelectasis, cerebral hemorrhage). The results suggest that meconium does not potentiate the constricting action of dopamine, serotonin and ethanol in tracheobronchial system. Meconium causes mild relaxation of the TSM through a mechanism that is not intermediated by the products of cyclooxygenases (prostaglandins, prostacyclins) from the tracheal epithelium or proteins. Also, as it seems, the direct activity of many tested acids in the smooth musculature has no significant impact on increase of the airways tonus in MAS syndrome. PMID:20002002

    Sometimes, antitussives can be a valid adjuvant to respiratory tract infections treatment. Although not always needed, this therapeutic support can be extremely useful in selected cases, and when patient is resident and monitored. In this line, the efficacy of a new peripheral antitussive, levodropropizine (Dompé farmaceutici, Milan), has been evaluated in 70 children inpatients of the Pediatric Department at san Paolo Hospital - Milan University - from September 1987 to May 1988. Thirty one male and 29 female children, aged 4 years and 6 months +/- 3 years and 5 months, suffering from various respiratory tract diseases were included in the study. Underlying diseases were represented by 21 acute bronchitis, 20 asthmatic attacks, 18 bronchopneumonia, 11 tracheitis, 6 acute episodes of chronic bronchitis, 2 hypoglottis laryngitis, 1 pertussis, 1 spontaneous pneumothorax. All parents gave their oral informed consent. The basic treatments were antibiotics in 44 patients associated or not with beta 2 agonists (31), theophylline (15), corticosteroids via aerosol (9) or parenterally (3), immunomodulators (2). Treatment with levodropropizine in the oral drops formulation at 2 mg pro kg a day was continued for 5 days and withdrawn according to the clinical evolution. Cough was registered by means of appropriate record forms given to the parents as well as with 120' tape recording whenever possible, i.e. 60 minutes before and 60 minutes after drug administration, on day one and 2. At treatment end, parents and investigator gave an antitussive efficacy judgement. Tolerability was evaluated as per clinical evolution and laboratory parameters. PMID:2631057

    Producer reports from ranches over 2,438 meters in southwest Colorado suggest that the mortality of preweaned beef calves may be substantially higher than the national average despite the selection of low pulmonary pressure herd sires for over 20 years. Diagnostic investigations of this death loss problem have been limited due to the extensive mountainous terrain over which these calves are grazed with their dams. The objective of the current study was to determine the causes of calf mortality on 5 high-altitude ranches in Colorado that have been selectively breeding sires with low pulmonary pressure (branding (6 weeks of age) in the spring to weaning in the fall (7 months of age). Clinical signs were recorded, and blood samples were taken from sick calves. Postmortem examinations were performed, and select tissue samples were submitted for aerobic culture and/or histopathology. On the principal study ranch, 9.6% (59/612) of the calves that were branded in the spring either died or were presumed dead by weaning in the fall. In total, 28 necropsies were performed: 14 calves (50%) had lesions consistent with pulmonary hypertension and right-sided heart failure, and 14 calves (50%) died from bronchopneumonia. Remodeling of the pulmonary arterial system, indicative of pulmonary hypertension, was evident in the former and to varying degrees in the latter. There is a need to better characterize the additional risk factors that complicate pulmonary arterial pressure testing of herd sires as a strategy to control pulmonary hypertension. PMID:23512918

    Aspiration pneumonia is a life-threatening infectious disease often caused by oral anaerobic and periodontal pathogens such as Porphyromonas gingivalis. This organism produces proteolytic enzymes, known as gingipains, which manipulate innate immune responses and promote chronic inflammation. Here, we challenged mice with P. gingivalis W83 and examined the role of gingipains in bronchopneumonia, lung abscess formation, and inflammatory responses. Although gingipains were not required for P. gingivalis colonization and survival in the lungs, they were essential for manifestation of clinical symptoms and infection-related mortality. Pathologies caused by wild-type (WT) P. gingivalis W83, including hemorrhage, necrosis, and neutrophil infiltration, were absent from lungs infected with gingipain-null isogenic strains or WT bacteria preincubated with gingipain-specific inhibitors. Damage to lung tissue correlated with systemic inflammatory responses, as manifested by elevated levels of TNF, IL-6, IL-17, and C-reactive protein. These effects were unequivocally dependent on gingipain activity. Gingipain activity was also implicated in the observed increase in IL-17 in lung tissues. Furthermore, gingipains increased platelet counts in the blood and activated platelets in the lungs. Arginine-specific gingipains made a greater contribution to P. gingivalis-related morbidity and mortality than lysine-specific gingipains. Thus, inhibition of gingipain may be a useful adjunct treatment for P. gingivalis-mediated aspiration pneumonia. PMID:26613585

  18. Botulinum toxin A for trismus in cephalic tetanus

    Full Text Available Cephalic tetanus is a localized form of tetanus. As in generalized forms , trismus is a prominent feature of the disease, leading to considerable difficulty in feeding, swallowing of the saliva and mouth hygiene. These difficulties often precede respiratory problems and aspiration bronchopneumonia is a frequent life-threatening complication. Muscle relaxants other than curare drugs may show a limited benefit for relieving trismus. Tetanospasmin, the tetanic neurotoxin, and botulinum toxin share many similarities, having a closely related chemical structure, an origin from related microorganisms (Clostridium tetani and Clostridium botulinum, respectively, and presumably, the same mechanisms of action in the neuron. The difference between the two lies in their peculiar neurospecificity, acting in different neurons. Injection of minute doses of botulinum toxin in the muscles involved in focal dystonias or other localized spastic disorders have proved to be very effective in these conditions. We describe the use of botulinum toxin A in the successful treatment of trismus in a patient suffering from cephalic tetanus. We believe that this form of treatment may be of value in lowering the risk of pulmonary complications in tetanic patients.

    Rhodococcus equi is a facultative intracellular bacterium that can cause bronchopneumonia in foals and AIDS patients. Here, we have analyzed R. equi-containing vacuoles (RCVs) in murine macrophages by confocal laser scanning microscopy, by transmission electron microscopy and by immunochemistry upon purification. We show that RCVs progress normally through the early stages of phagosome maturation acquiring PI3P, early endosome antigen-1, and Rab5, and loosing all or much of them within minutes. Although mature RCVs possess the normally late endocytic markers, lysosome-associated membrane proteins, lysobisphosphatidic acid and Rab7, they lack other hallmark features of late endocytic organelles such as possession of cathepsin D, acid beta-glucuronidase, proton-pumping ATPase and the ability to fuse with prelabeled lysosomes. Bacterial strains possessing a virulence-associated plasmid maintain a nonacidified compartment for 48 h, whereas isogenic strains lacking such plasmids acidify progressively. In summary, RCVs represent a novel phagosome maturation stage positioned after completion of the early endosome stage and before reaching a fully mature late endosome compartment. In addition, vacuole biogenesis can be influenced by bacterial plasmids. PMID:15998320

    Full Text Available BACKGROUND: Maternal mortality is a major public-health problem in developing countries. Extreme differences in maternal mortality rates between developed and developing countries indicate that most of these deaths are preventable. Most information on the causes of maternal death in these areas is based on clinical records and verbal autopsies. Clinical diagnostic errors may play a significant role in this problem and might also have major implications for the evaluation of current estimations of causes of maternal death. METHODS AND FINDINGS: A retrospective analysis of clinico-pathologic correlation was carried out, using necropsy as the gold standard for diagnosis. All maternal autopsies (n = 139 during the period from October 2002 to December 2004 at the Maputo Central Hospital, Mozambique were included and major diagnostic discrepancies were analyzed (i.e., those involving the cause of death. Major diagnostic errors were detected in 56 (40.3% maternal deaths. A high rate of false negative diagnoses was observed for infectious diseases, which showed sensitivities under 50%: HIV/AIDS-related conditions (33.3%, pyogenic bronchopneumonia (35.3%, pyogenic meningitis (40.0%, and puerperal septicemia (50.0%. Eclampsia, was the main source of false positive diagnoses, showing a low predictive positive value (42.9%. CONCLUSIONS: Clinico-pathological discrepancies may have a significant impact on maternal mortality in sub-Saharan Africa and question the validity of reports based on clinical data or verbal autopsies. Increasing clinical awareness of the impact of obstetric and nonobstetric infections with their inclusion in the differential diagnosis, together with a thorough evaluation of cases clinically thought to be eclampsia, could have a significant impact on the reduction of maternal mortality.

Objective: to describe aspects related with hidden mortality by cerebrovascular diseases in Intermediate Care Unit. Method: Descriptive and retrospective study of a series of cases carried out during the period 2002-2004 in the hospital ¨Dr. Gustavo Aldereguía Lima¨ of Cienfuegos. All monthly reports of the cerebrovascular diseases attention group were analysed, these being gathered from digitalized data bases from the Hospital Statistics Department (n=3477. An enquiry was applied to obtain information as: year and month of hospitalisation; egress state; decease place if in case; stay; and type of cerebrovascular disease. The deceased necropsy protocols were analysed. Results: The hidden mortality was of 0.05; the main causal entity was the cerebral infarction (71,87%, the behaviour was similar in the five years, the average stay of deceased patients in Intermediate Care Unity was of 4.2 days, and outside this Unity: 8.7 days. It was proved the reduced inn hospital hidden mortality caused by cerebrovascular diseases with lethality definition by these entities during the first days in progressive care. A reduced percent of patients died in other units where an average stay doubles that of the Intermediate Care Unit, and as the main cause: the polymorbility associated to bronchopneumonia.

    Full Text Available In order to assess the effect of air pollution on pediatric respiratory morbidity, we carried out a time series study using daily levels of PM10, SO2, NO2, ozone, and CO and daily numbers of pediatric respiratory emergency room visits and hospital admissions at the Children's Institute of the University of São Paulo Medical School, from August 1996 to August 1997. In this period there were 43,635 hospital emergency room visits, 4534 of which were due to lower respiratory tract disease. The total number of hospital admissions was 6785, 1021 of which were due to lower respiratory tract infectious and/or obstructive diseases. The three health end-points under investigation were the daily number of emergency room visits due to lower respiratory tract diseases, hospital admissions due to pneumonia, and hospital admissions due to asthma or bronchiolitis. Generalized additive Poisson regression models were fitted, controlling for smooth functions of time, temperature and humidity, and an indicator of weekdays. NO2 was positively associated with all outcomes. Interquartile range increases (65.04 µg/m³ in NO2 moving averages were associated with an 18.4% increase (95% confidence interval, 95% CI = 12.5-24.3 in emergency room visits due to lower respiratory tract diseases (4-day moving average, a 17.6% increase (95% CI = 3.3-32.7 in hospital admissions due to pneumonia or bronchopneumonia (3-day moving average, and a 31.4% increase (95% CI = 7.2-55.7 in hospital admissions due to asthma or bronchiolitis (2-day moving average. The study showed that air pollution considerably affects children's respiratory morbidity, deserving attention from the health authorities.

  5. A SUBCHRONIC INHALATION STUDY OF FISCHER 344 RATS EXPOSED TO 0, 0.4, 1.4 OR 4.0 PPM ACROLEIN

    International Nuclear Information System (INIS)

    Fischer 344 rats were exposed to 0.0, 0.4, 1.4, or 4.0 ppm acrolein for 62 days. The major objective of the study was to relate the results of a series of pulmonary function tests to biochemical and pathological alterations observed in the lung. Cytological and reproductive potential endpoints were also assessed after acrolein exposure. Rats were exposed to acrolein for 6 hours/day, 5 days/week for 62 days. Mortality was observed only in the 4.0 ppm chamber where 32 of 57 exposed males died; however, none of the 8 exposed females died. Most of the mortality occurred within the first 10 exposure days. Histologic examination indicated that the animals died of acute bronchopneumonia. The surviving males and females exposed to 4.0 ppm acrolein gained weight at a significantly slower rate than control animals. The growth of both sexes in the 0.4 and 1.4 ppm groups was similar to that of their respective controls. Histopathologic examination of animals after 62 days of exposure revealed bronchiolar epithelial necrosis and sloughing, bronchiolar edema with macrophages, and focal pulmonary edema in the 4.0 ppm group. These lesions were, in some cases, associated with edema of the trachea and peribronchial lymph nodes, and acute rhinitis which indicated an upper respiratory tract effect of acrolein. Of particular interest was the variability of response between rats in the 4.0 ppm group, some not affected at all while others were moderately affected. Intragroup variability in toxicity was also apparent in the 1.4 ppm exposure group where only 3 of 31 animals examined had lesions directly related to acrolein exposure. Extra respiratory organs appeared unaffected

    Orientia tsutsugamushi, the causative agent of scrub typhus, is an obligate intracellular bacterium and characterized by dramatic genetic diversity. To elucidate the genotypes of O. tsutsugamushi populating in patients in Shandong Province, a new epidemic zone in China, we sequenced partial of the 56-kDa type-specific antigen gene (TSA) and identified the genotypes of 43 O. tsutsugamushi samples from human patients confirmed with scrub typhus from 2010 to 2013. All of the 43 sequences are in the same clade, 39 of them are in one branch and the other four sequences, nominated as SH1002, SH1306, SH1309, and SH1307 are in four separate branches. To clarify the clinical characterizations caused by Kawasaki-related genotypes, we studied the clinical profiles of these 43 scrub typhus patients. Most patients (88.1%) were farmers lived in rural areas. They presented with fever (100.0%), headache (79.1%), dizziness (32.6%), generalized myalgia (48.8%), fatigue (53.5%), anorexia (53.5%), facial flushing (23.3%), conjunctival congestion (11.6%), skin rashes (58.1%) and lymphadenopathy (23.3%). Eschar (97.7%) was quite common in patients, which provided doctors with a luminous clue for diagnosis of scrub typhus. Thrombocytopenia was seen in 23.1% of patients, and three patients (7.0%) had bronchopneumonia. There was no death report in Shandong Province during the study period. The present study provides beneficial data for clinical, serological, and molecular diagnosis of scrub typhus infections, and also provides foundations for subsequent studies. PMID:25575441

    Recurrent pharyngo-tonsillar infections caused by group A beta-hemolytic streptococci (GABHS) occur frequently in young children, and the treatment of these infections contributes substantially to the total current requirement for antibiotic prescribing. Our study goal was to assess through a retrospective observational analysis whether the administration of the oral probiotic, Streptococcus salivarius K12 (SsK12), could reduce the occurrence of GABHS pharyngo-tonsillar infections in children who had a recent history of recurrent episodes of these infections. Twelve primary care pediatricians identified, through their databases, a total of 130 children who had experienced recurrent GABHS pharyngo-tonsillar infections over a period of at least 6-12 months prior to their inclusion in the study. Of these children, 76 then undertook a 90-day program requiring once-a-day dosing with a commercially available (Bactoblis) lozenge containing SsK12. No probiotic supplement was given to the remaining 54 (control) children. Each subject was monitored for the occurrence of GABHS pharyngo-tonsillitis and also for acute otitis media, bronchitis, sinusitis, and bronchopneumonia for at least 12 months following their entry to the study. Even 9 months after the use of SsK12 had been stopped, the probability of new GABHS infections was significantly lower (P>0.001) when compared to the period before dosing commenced. When compared to the untreated children, those taking SsK12 appear to have had significantly fewer GABHS infections both during the 90-day period of prophylaxis and during the following 9 months (P<0.001). These observations are supportive of the use of probiotic SsK12 for the control of recurrent GABHS pharyngo-tonsillar infections in children, and as an associated benefit, the use of this probiotic could lead to reduced antibiotic consumption. Follow-up controlled prospective studies should now be initiated in order to further establish the efficacy of this newly

    Full Text Available Se describen dos casos de aborto viral equino, un feto abortado al final de la gestación y el otro nacido y muerto 24 horas después, provenientes de un predio que presentó otros 6 abortos más en la temporada de partos del año 1996. En la necropsia de ambos se observó ictericia, hemorragias oral y nasal, hemorragias de los linfonódulos, congestión general, pleuritis serofibrinosa, edema pulmonar, bronconeumonía catarral en los lóbulos apicales, ascitis, esplecnomegalia, necrosis del hígado y nefrosis. La histopatología y microscopía electrónica revelaron la existencia de cuerpos de inclusión intranucleares de tipo A de Cowdry en células epiteliales del pulmón, hepatocitos y macrófagos del bazo. Estos antecedentes son semejantes a lo descrito en aborto viral herpético o rinoneumonitis equina.Two cases of equine viral abortion are described: one foetus which was miscarried at the end of the pregnancy and the other which was born and died 24 hs later. Both cases came from a farm that had had 6 mare miscarriages during the 1996 birth period. The following lesions were observed in the necropsy: icterus, oral and nasal haemorrhages, lymphoid haemorrhages, general congestion, serophibrinous pleuritis, lung oedema, catarrhs bronchopneumonia at the apical lobes, ascitis, enlarged spleen, liver necrosis and nephrosis. Histopathology and electron microscopy indicated the presence of intranuclear inclusion bodies Cowdry type A in the epithelial cells of the lung, hepatocytes and macrophages of the spleen. All of the lesions are similar to those described in equine viral abortion or equine rhinopneumonitis

    Full Text Available Harbour seals (Phoca vitulina are frequently infected with the lungworms Otostrongylus circumlitus and Parafilaroides gymnurus. The infection is often accompanied by secondary bacterial infections and can cause severe bronchopneumonia and even death in affected animals. Hitherto, the detection of lungworm infections was based on post mortem investigations from animals collected within stranding networks and a valid detection method for live free-ranging harbour seals was not available. Recently, an ELISA was developed for detecting lungworm antibodies in harbour seal serum, using major sperm protein (MSP of the bovine lungworm, Dictyocaulus viviparus as recombinant diagnostic antigen. To determine lungworm seroprevalence in free-ranging harbour seals, serum was taken from four different seal age groups (n = 313 resulting in an overall prevalence of 17.9% (18.9% of males, 16.7% of females. 0.7% of harbour seals up to six weeks of age were seropositive, as were 89% of seals between six weeks and six months, 53.6% between six and 18 months and 24.2% of seals over 18 months of age. In the 18 months and over age group, seropositive animals showed statistically significant reductions in body weight (P = 0.003 and length (P < 0.001. Sera from lungworm infected harbour seals in rehabilitation (n = 6 revealed that duration of antibody persistence may be similar to that of lungworm infected cattle, but further studies are needed to confirm this. Phylogenetic analyses of MSP sequences of different marine and terrestrial mammal parasitic nematodes revealed that lungworm MSP of the genus Dictyocaulus (superfamily Trichostrongyloidea is more closely related to metastrongylid marine mammal lungworms than to trichostrongylid nematodes of terrestrial hosts.

  11. Analysis of perfusion defects by causes other than acute pulmonary thromboembolism on contrast-enhanced dual-energy CT in consecutive 537 patients

    International Nuclear Information System (INIS)

    Objective: To assess causes, incidence and patterns of perfusion defects (PDs) on dual-energy perfusion CT angiography (DECTA) in clinically suspected acute pulmonary thromboembolisms (PTE). Materials and methods: Consecutive 537 patients who underwent DECTA for suspicion of PTE were retrospectively reviewed. After excluding patients with possible PTE or unsatisfactory perfusion map quality, 299 patients with 1697 lobes were included. The DECTA (Somatom Definition, Siemens) was performed at 140 kV and 80 kV. Color-coded perfusion images were obtained with a lung PBV application of the workstation software (Syngo Dual Energy). The presence, incidence, three patterns of PDs (wedge-shaped, heterogeneous, and regionally homogeneous), pulmonary diseases, and the matchedness between the PD and the disease extent were studied. Results: 315 of 1697 lobes (18.6%) in 156 of 299 patients (81.3%) showed PDs. Among them, 51 (3%), 257 (15.1%), and 7 (0.4%) lobes had PDs due to vascular, nonvascular, and unidentifiable causes, respectively. Vascular causes include: pulmonary arterial (PA) hypertension (0.7%), extrinsic occlusion of PA by fibrosis (0.6%), PA hypoplasia (0.6%), vasculitis (0.5%), cancer mass compressing PA, venous occlusion, AVM, and pulmonary angiosarcoma. Most of PDs were wedge-shaped and well-matched. Nonvascular causes include: mosaic attenuation (4.1%), emphysema (3.2%), interstitial fibrosis (1.6%), bronchitis (1.4%), GGO (1.2%), cellular bronchiolitis (1%), bronchiectasis, airway obstruction, compensaroty lung hyperinflation, air trapping, cor-pulmonale, bronchopneumonia, physiologic decreased ventilation, and segmental bronchial atresia. Most of PDs showed heterogeneous pattern and were not matched. Conclusions: Various vascular and nonvascular diseases cause PDs on DECTA. Each disease shows different pattern of PD depending on pathophysiology and physiologic compensation.

    Human bocavirus (HBOV) has been reported as a worldwide distributed respiratory pathogen. It has also been associated with encephalitis recently by detection of the virus in cerebrospinal fluid (CSF) of patients presented with encephalitis. This retrospective study aimed to present clinical features of HBOV infections in children with respiratory symptoms and describe unexplained encephalopathy in a subgroup of these patients. Results of 1,143 pediatric nasal samples from mid-December 2013 to July 2014 were reviewed for detection of HBOV. A multiplex real time polymerase chain reaction assay was used for viral detection. Medical records of the patients were retrospectively analyzed. HBOV was detected in 30 patients (2.6%). Median age was 14 months (5-80). Clinical diagnoses were upper respiratory tract infection (n = 10), bronchopneumonia (n = 9), acute bronchiolitis (n = 5), pneumonia (n = 4), acute bronchitis (n = 1), and asthma execarbation (n = 1). Hospitalization was required in 16 (53.3%) patients and 10 (62.5%) of them admitted to pediatric intensive care unit (PICU). Noninvasive mechanical ventilation modalities was applied to four patients and mechanical ventilation to four patients. Intractable seizures developed in four patients while mechanically ventilated on the 2nd-3rd days of PICU admission. No specific reason for encephalopathy was found after a thorough investigation. No mortality was observed, but two patients were discharged with neurological sequela. HBOV may lead to respiratory infections in a wide spectrum of severity. This report indicates its potential to cause severe respiratory infections requiring PICU admission and highlights possible clinical association of HBOV and encephalopathy, which developed during severe respiratory infection.

  13. Development and characterization of a caprine aerosol infection model of melioidosis.

    Carl Soffler

    Full Text Available Infection with Burkholderia pseudomallei causes the disease melioidosis, which often presents as a serious suppurative infection that is typically fatal without intensive treatment and is a significant emerging infectious disease in Southeast Asia. Despite intensive research there is still much that remains unknown about melioidosis pathogenesis. New animal models of melioidosis are needed to examine novel aspects of pathogenesis as well as for the evaluation of novel therapeutics. The objective of the work presented here was to develop a subacute to chronic caprine model of melioidosis and to characterize the progression of disease with respect to clinical presentation, hematology, clinical microbiology, thoracic radiography, and gross and microscopic pathology. Disease was produced in all animals following an intratracheal aerosol of 10(4 CFU delivered, with variable clinical manifestations indicative of subacute and chronic disease. Bronchointerstitial pneumonia was apparent microscopically by day 2 and radiographically and grossly apparent by day 7 post infection (PI. Early lesions of bronchopneumonia soon progressed to more severe bronchointerstitial pneumonia with pyogranuloma formation. Extrapulmonary dissemination appeared to be a function of pyogranuloma invasion of pulmonary vasculature, which peaked around day 7 PI. Histopathology indicated that leukocytoclastic vasculitis was the central step in dissemination of B. pseudomallei from the lungs as well as in the establishment of new lesions. While higher doses of organism in goats can produce acute fatal disease, the dose investigated and resulting disease had many similarities to human melioidosis and may warrant further development to provide a model for the study of both natural and bioterrorism associated disease.

    Full Text Available Melioidosis es una enfennedad infecciosa causada por la Burkholderia pseudomallef. Esta enfermedad es endémica en áreas tropicales de Asia y Australia y ha habido reportes aislados en Centro y Sur América. Aquí nosotros informamos del primer caso probado de melioidosis en Costa Rica, correspondiendo a un paciente sin historia de viajes a lugares endémicos. El paciente consultó por una bronconeumonía de adquisición comunitaria y sepsis. El hecho que el aislamiento bacteriano sea tan inusual en nuestro país implicó un retraso subsecuente en el inicio del tratamiento antibiótico específico en este caso, lo cual pudo influir en la evolución tan tórpida del paciente. Esto nos plantea el interrogante de si esta enfermedad debe ser incluida en el diagnóstico diferencial de sepsis de adquisición comunitaria en nuestro país.Melioidosis in an infectious disease caused by Burkholderia pseudomallei. This disease is endemie in areas of tropical Asia and Australia; there have been isolated reports of the disease in Central and South America. Here we report the first documented case of Melioidosis in Costa Rica in a patient without a history of traveling lo endemic areas. The patient was seen at the hospital because of sepsis and a community acquired bronchopneumonia. Due lo the rareness of this bacterial isolation in our country the corroboration of the diagnosis was delayed and subsequently the specific antibiotics were started 5 days later after the admission, this could have influenced the torpid evolution the patient had. This case should alert us and points lo the need of including this rare disease in the differential diagnosis of community acquired sepsis in our country.

    Full Text Available Abstract Background Coxsackievirus A9 (CA9 was one of the most prevalent serotype of enteroviral infections in Taiwan in 2011. After several patient series were reported in the 1960s and 1970s, few studies have focused on the clinical manifestations of CA9 infections. Our study explores and deepens the current understanding of CA9. Methods We analyzed the clinical presentations of 100 culture-proven CA9-infected patients in 2011 by reviewing their medical records and depicted the CA9 phylogenetic tree. Results Of the 100 patients with culture-proven CA9 infections, the mean (SD age was 4.6 (3.4 years and the male to female ratio was 1.9. For clinical manifestations, 96 patients (96% had fever and the mean (SD duration of fever was 5.9 (3.4 days. Sixty one patients (61% developed a skin rash, and the predominant pattern was a generalized non-itchy maculopapular rash without vesicular changes. While most patients showed injected throat, oral ulcers were found in only 19 cases (19%, among whom, 6 were diagnosed as herpangina. Complicated cases included: aseptic meningitis (n=8, bronchopneumonia (n=6, acute cerebellitis (n=1, and polio-like syndrome (n=1. Phylogenetic analysis for current CA9 strains is closest to the CA9 isolate 27-YN-2008 from the border area of mainland China and Myanmar. Conclusions The most common feature of CA9 during the 2011 epidemic in Taiwan is generalized febrile exanthema rather than herpangina or hand, foot, and mouth disease. Given that prolonged fever and some complications are possible, caution should be advised in assessing patients as well as in predicting the clinical course.

    Full Text Available Cystic fibrosis (CF is the most common genetic disease among Caucasians and is rare among sub-Saharan Africans. The Brazilian population is not ethnically homogeneous but it is the result of three-way ethnic admixture of Europeans, Africans and Amerindians in varying proportions, depending on the region. In the present study, we investigated 33 patients who had been diagnosed and are currently under treatment for CF at the University Hospital João de Barros Barreto, Belém, Pará State. The molecular analysis for G542X, G551D and R553X mutations was performed by PCR followed by RFLP using BstNI, HincII and MboI, respectively, in polyacrylamide gel eletrophoresis and stained with AgNO3. ThedeltaF508 mutation (a deletion of 3 bp was only analyzed by polyacrylamide gel electrophoresis and stained with AgNO3. Each sample was analyzed for regions of interest in the CFTR gene using amplified by PCR and specific primers. The deltaF508 and G551D mutations presented frequencies of 22.7 and 3%, respectively. In 74.3% of the remaining patients, none of the mutations investigated was found. The present study characterized in a sample of patients with an established clinical diagnosis of CF (asthma, repeated bronchopneumonia, disorders of nutritional status, etc. the most frequent mutation ( deltaF508 in the North region of Brazil and is also the first report of the G551D mutation. In spite of the wide spectrum of CF mutations and the heterogeneous ethnic origin of the Amazon population, the molecular diagnosis is a helpful additional tool for the diagnosis and treatment of CF patients.

    Fischer 344 rats were exposed to 0.0, 0.4, 1.4, or 4.0 ppm acrolein for 62 days. The major objective of the study was to relate the results of a series of pulmonary function tests to biochemical and pathological alterations observed in the lung. Cytological and reproductive potential endpoints were also assessed after acrolein exposure. Rats were exposed to acrolein for 6 hours/day, 5 days/week for 62 days. Mortality was observed only in the 4.0 ppm chamber where 32 of 57 exposed males died; however, none of the 8 exposed females died. Most of the mortality occurred within the first 10 exposure days. Histologic examination indicated that the animals died of acute bronchopneumonia. The surviving males and females exposed to 4.0 ppm acrolein gained weight at a significantly slower rate than control animals. The growth of both sexes in the 0.4 and 1.4 ppm groups was similar to that of their respective controls. Histopathologic examination of animals after 62 days of exposure revealed bronchiolar epithelial necrosis and sloughing, bronchiolar edema with macrophages, and focal pulmonary edema in the 4.0 ppm group. These lesions were, in some cases, associated with edema of the trachea and peribronchial lymph nodes, and acute rhinitis which indicated an upper respiratory tract effect of acrolein. Of particular interest was the variability of response between rats in the 4.0 ppm group, some not affected at all while others were moderately affected. Intragroup variability in toxicity was also apparent in the 1.4 ppm exposure group where only 3 of 31 animals examined had lesions directly related to acrolein exposure. Extra respiratory organs appeared unaffected.

    Full Text Available Introduction. Brucellosis is an acute, subacute or chronical disease, from the zoonosis group, caused by various types of bacteria belonging to genus Brucellae. It is transmitted to humans from domestic animals: goats, sheep, cattle, pigs and dogs. The course of the disease may either be asymptomatic, or produce a variety of clinical manifestations, ranging from light ones to extremely severe clinical forms. The aim of the study was to follow the clinical features of brucella infection in the hospital-treated patients, as well as its course and outcome. Material and Methods. The investigation included 15 patients, treated for brucella infection at the Clinic for infectious diseases during the last two years (2004 and 2005. Results. All patients were adults, their age ranged from 18 to 71, 49.96 on average. The epidemiological questionnaire was positive in all patients, confirming contacts with the ailing animals, or consumption of cheese made from milk of diseased animals. They all exhibited the classic symptoms - increased body temperature and shiver, fever, sweating, malaise and headache, the so called flu like state. The serum agglutination test was positive in respect to brucellosis, the titre ranged from 1:80 to 1:1280. Eight patients suffered excessive back pain, accompanied with impeded walk. In half of them magnetic resonance imaging confirmed the spondylodiscitis diagnosis. Three patients had clinical features of knee arthritis, two had bronchopneumonia, one pancreatitis, and one developed the signs of an acute kidney insufficiency. The outcome was favorable in all patients - They recuperated or healed completely. In one patient a relapse occurred, leading to the chronic course of the illness. Discussion. Although predominantly Mediterranean Brucellosis is a worldwide spread disease. During the last two years, an increased incidence of the disease has been observed. Conclusion.

    The identification and distinction of the pathological conditions underlying acute psychosis are often challenging. We present the case of a 35-year-old ranger who had no history of acute or chronic infectious disease or any previous neuropsychiatric symptoms. He arrived at the Psychiatry Clinic and was admitted as an emergency case, displaying bizarre behavior, hallucinations, paranoid ideation, and delusional faults. These symptoms had first appeared 7 days earlier. An objective examination revealed abnormalities of behavior, anxiety, visual hallucinations, choreiform, and tic-like facial movements. After the administration of neuroleptic and antidepressant treatment, he showed an initial improvement, but on day 10 entered into a severe catatonic state with signs of meningeal irritation and was transferred to the intensive care unit. An electroencephalogram showed diffuse irritative changes, raising the possibility of encephalitis. Taking into consideration the overt occupational risk, Borrelia antibody tests were prescribed and highly positive immunoglobulin (Ig)M and IgG titers were obtained from serum, along with IgG and antibody index positivity in cerebrospinal fluid. In parallel, anti-N-methyl-D-aspartate receptor antibodies and a whole battery of other autoimmune encephalitis markers showed negative. A complex program of treatment was applied, including antibiotics, beginning with ceftazidime and ciprofloxacin – for suspected aspiration bronchopneumonia – and thereafter with ceftriaxone. A gradual improvement was noticed and the treatment continued at the Infectious Disease Clinic. Finally, the patient was discharged with a doxycycline, antidepressant, and anxiolytic maintenance treatment. On his first and second control (days 44 and 122 from the disease onset), the patient was stable with no major complaints, Borrelia seropositivity was confirmed both for IgM and IgG while the cerebrospinal fluid also showed reactivity for IgG on immunoblot.

    Bruton's agammaglobulinemia is a primary immunodeficiency with a disease onset during the first months of age, when the maternal serum immunoglobulin levels decrease. It is characterized by recurrent infections and agammaglobulinemia. We report the case of a 6-year-old male patient with third-degree consanguinity, product of a third pregnancy and complete immunization scheme. He had a history of oral candidiasis at the age of 3 months, chicken pox at the age of 7 months, and two episodes of complicated bronchopneumonia at the age of 1 year and 6 years. He was admitted to the hospital because of fever and cough. Examination of the chest showed rales and right basilar hypoventilation, and a blood cell count revealed leukocytosis and neutrophilia. The diagnosis of pneumonia was made. He was treated with IV antibiotics. Serum immunoglobulins were reported to be low (IgM 55 mg/dL, IgA 0.9 mg/dL, and IgG 199 mg/dL). With these findings the clinical diagnosis of X-linked agammaglobulinemia (ALX) was concluded. A molecular test was performed fining a BTK gene confirming the diagnosis of Bruton's disease. Therapy with intravenous IgG was started every 21 days. During his evolution, he presented three episodes of rhinosinusitis, one of suppurative otitis media, and four events of pneumonia that required 37 days of hospitalization. After hospital discharge, the patient was free of infections and he returned to his daily activities. In cases of recurrent and severe respiratory infections in children, we must consider primary immunodeficiency disease in the differential diagnosis, mainly antibiotic deficiency. Early diagnosis and treatment improves the survival and quality of life in these patients. PMID:21854727

  2. Marcel Proust's diseases and doctors: the neurological story of a life.

    Marcel Proust (1871-1922), one of the greatest writers of all times, suffered from asthma beginning at age 9, in an era when the illness was considered a 'nervous' disorder belonging to what Beard, in 1870, called 'neurasthenia'. Proust's father, Adrien, was himself a professor of medicine (hygiene) who had met Charcot, and who contributed to neurology with studies on aphasia, stroke, hysteria, and neurasthenia - a condition about which he, along with Gilbert Ballet, published a book in 1897. Through his father, Proust met Edouard Brissaud, the co-founder of the Revue Neurologique in 1893, and, in 1896, the author of The Hygiene of the Asthmatics, with a foreword by Adrien Proust. Shortly after his mother's death in 1905, Proust contemplated admitting himself to a private hospital to reset his irregular sleep patterns and to improve his asthma. He hesitated in his choice of care between Jules Dejerine in Paris, Henry-Auguste Widmer at Valmont, and Paul Dubois in Bern. Finally, he decided to enter Paul Sollier's clinic, in Boulogne-sur-Seine, on the advice of Brissaud, and stayed there for 6 weeks in semi-isolation. Together with Babinski, Sollier was, at that time, considered the most gifted follower of Charcot. He was a forerunner of studies on emotional memory, which strongly influenced Proust. In Proust's opus magnum work In Search of Lost Time, 'involuntary memory' indeed forms the core mechanism of the entire novel, counterbalancing the decaying effects of time. A few years before his death from complicated bronchopneumonia at age 52, Proust became terrified of developing a stroke, like his mother and father, and he consulted with Joseph Babinski, who tried to reassure him. Proust's life followed an unusual neurological itinerary, which has been largely overlooked, but which is in fact critical for an understanding of his literary work. PMID:17495507

    In the United States in the 1930s, although the pathogen was not known, atypical pneumonia was clinically distinguished from pneumococcal pneumonia by its resistance to sulfonamides. Reimann (1938) reported seven patients with an unusual form of tracheo bronchopneumonia and severe constitutional symptoms. He believed the clinical picture of this disease differed from that of the disease caused by influenza viruses or known bacteria and instead suspected "primary atypical pneumonia." For many years, the responsible infectious agent was tentatively classified as a filterable virus that could pass through a Seitz filter to remove bacteria and was reported to be a psittacosis-like or new virus. After that, Eaton et al. (1942, 1944, 1945) identified an agent that was the principal cause of primary atypical pneumonia using cotton rats, hamsters, and chick embryos. Eaton et al. (1942, 1944, 1945) did not perform an inoculation study in human volunteers. During the 1940s, there were three groups engaged in discovering the etiology of the primary atypical pneumonia. (1) Commission on Acute Respiratory Diseases Diseases directed by John Dingle, (2) Dr. Monroe Eaton's group, the Virus Research Laboratory of the California State Public Health Department, (3) The Hospital of the Rockefeller Institute for Medical Research directed by Horsfall. During 1940s, the members of the Commission on Acute Respiratory Diseases concluded that the bacteria-free filtrates obtained from the patients, presumably containing a virus, could induce primary atypical pneumonia in human volunteers via Pinehurst trials. During 1950s, serological approaches for identification of the Eaton agent developed such as Fluorescent-Stainable Antibody, and at the beginning of the1960s, the Eaton agent successfully grew in media, and finally accepted as a cause of primary atypical pneumonia. Thus, technical difficulties with visualizing the agent and failure to recognize the full significance of the Pinehurst

  4. T-2 toxin impairs murine immune response to respiratory reovirus and exacerbates viral bronchiolitis

    International Nuclear Information System (INIS)

    Exposure to immunosuppressive environmental contaminants is a possible contributing factor to increased occurrence of viral respiratory diseases. The objective of this study was to test the hypothesis that the trichothecene mycotoxin T-2 toxin (T-2), a frequent food contaminant, alters host resistance to lung infection by reovirus, a model respiratory virus. Balb/c mice (4 week old) were treated intraperitoneally with T-2 toxin (1.75 mg/kg bw) or saline vehicle and then intranasally instilled 2 h later with 107 plaque forming unit (PFU) of reovirus, strain Lang (T1/L) or saline vehicle. At 10 days post-instillation (PI), both virus plaque-forming responses and reovirus L2 gene expression were 10-fold higher in lungs of T-2-treated mice compared to controls. No-effect and lowest-effect levels for T-2-induced suppression of reovirus clearance were 20 and 200 μg/kg bw, respectively. Respiratory reovirus infection resulted in a mild bronchiolitis with minimal alveolitis, which was markedly exacerbated by T-2 pretreatment. Reovirus exposure induced marked increases in total cells, neutrophils and lymphocytes at 3 and 7 days PI in bronchial alveolar lavage fluid (BALF) whereas macrophages were increased only at 7 days PI. Although prior T-2 exposure attenuated total cell and macrophage counts in BALF of control and infected mice at 3 days PI, the toxin potentiated total cell, macrophage, neutrophil and lymphocyte counts in infected mice at 7 days PI. At 3 days PI, T-2 suppressed reovirus-induced IFN-γ elevation in BALF, but enhanced production of IL-6 and MCP-1. T-2 pretreatment also suppressed reovirus-specific mucosal IgA responses in lung and enteric tract, but potentiated serum IgA and IgG responses. Taken together, T-2 increased lung viral burden, bronchopneumonia and pulmonary cellular infiltration in reovirus-infected mice. These effects might be attributable to reduced alveolar macrophage levels as well as modulated cytokine and mucosal Ig responses

    The aim of study was to necropsy and histopathology evaluation of lung Crenosoma striatum in hedgehog. In July 2012, 10 porcupines were collected from Urmia city and transferred to parasitology lab of the veterinary faculty where they were euthanized by ketamine (over 40-90 mg/kg) intraperitoneally. In this study the lungs were assessed through naked eyes regarding parasite presence upon washing. The lung tissue was examined under loop microscope in order to finding small worms in lung parenchyma. The worms were removed by Anse forceps and kept in AFA solution, and collected for diagnosis. In order to carrying out pathological tests, some samples prepared and placed in formalin 10 % for fixation. The counted worms frequency in high severe and moderate lungs were as 86 (50 females and 36 males) and 19 (13 females and 16 males) worms respectively. But no worms were observed in healthy lungs. The infestation severity was as; low infestation (1-7 worms), moderate infestation (8-20), severe infestation (21-50) and very severe infestation (more than 50 worms). The lung examinations of non-infested lungs indicated that the lung tissues had no parasite. In addition, no inflammation reactions as inflammatory cells presence were observed, and the air spaces with alveoles' wall in some regions were observable. On histopathological examination, the observed alteration was primarily inflammatory changes, and in some cases the proliferation was also observable. Hyperemia and inflammatory cell infiltration, somehow the alveolar space was filled, representing bronchopneumonia reaction. The bronchioles had various changes as hypertrophy and hyperplastic in different parts of respiratory system. Hyperemia and hemorrhage were very severe in some cases caused hemosiderosis in the lung. In severe inflammations the pneumonia along with increasing of bronchial cells in the lumen rose as well, leading to severe verminous infestation of the lung. In regard to the obtained results, the

    Full Text Available O presente relato descreve os achados clínicos e anatomopatológicos de um caso de amiloidose renal em um cão macho de nove anos da raça Shar-Pei. O animal apresentava quadro clínico de esporotricose e de insuficiência renal e exames positivos para erlichiose e leishmaniose. No dia anterior ao óbito, o cão apresentou apatia, desidratação e anúria. À necropsia foram observados inúmeros pontos milimétricos esbranquiçados localizados no córtex renal e hepatização do lobo diafragmático esquerdo. O achado histológico mais importante foi deposição de material eosinofílico, amorfo e acelular localizado nos tufos glomerulares que se corou positivamente pelo vermelho congo (amilóide. Observaram-se nefrite supurada multifocal, espessamento da cápsula de Bowman e broncopneumonia supurada crônica, com fibrose intensa. A origem da amiloidose, no presente caso, poderia ser hereditária, assemelhando-se à amiloidose familiar descrita em cães da raça Shar-Pei, ou ser devida à inflamação supurada crônica e/ou leishmaniose.The clinical and pathological findings of a case of renal amyloidosis in a nine-year-old male Shar-Pei dog were described. Clinically, there were signs of sporotrichosis and renal insufficiency, besides being positive to leishmaniasis and ehrlichiosis. On the day before death, the animal became apathetic, dehydrated and anuric. On gross examination, there were several whitish millimetric spots seen widespread in both renal cortices and consolidation of the left diaphragmatic pulmonary lobe. The most important microscopic finding was a deposition of amorphous acellular material on the glomerular tufts which stained positively by congo red stain. Other changes were multifocal suppurative nephritis, thickening of the Bowman capsule and chronic suppurative bronchopneumonia. The origin of the amyloidosis in this case could be hereditary, being similar to familiar amyloidosis described in Shar-Pei breed, or due to

    Infection with Penicillium marneffei has rarely been reported in human immunodeficiency virus (HIV)-negative infants. We aimed to determine the epidemiological, clinical, pathological, and immunological characteristics of 7 HIV-negative infants infected by P. marneffei, and to provide insights into its diagnosis and treatment.We retrospectively reviewed the cases of 7 HIV-negative infants infected by P. marneffei who presented to the First Affiliated Hospital of Guangxi Medical University between January 1, 2003 and December 1, 2014. The infants' median age was 23.43 months (SD = 8.34), and all lived in Guangxi Province in China, where P. marneffei is endemic. The median time from disease onset to diagnosis was 2.29 months (SD = 2.12). Of the cases studied, 5 (71.43%) had medical histories that included frequent pneumonia or bronchopneumonia, thrush, congenital megacolon, glucose-6-phosphate dehydrogenase deficiency, and hemophagocytic syndrome. The most common symptoms were fever, cough, and anemia, followed by lymphadenopathy, hepatosplenomegaly, and being underweight. Four patients had slightly elevated white blood cell counts. The lymphocyte and CD4 T-cell counts were normal. The CD8 T-cell counts, serum immunoglobulin (Ig) G titer, and serum IgA titer were low in 5 patients, and the serum IgM titers were high in 3 infants. Caseous necrosis was observed in 3 patients whose lymph nodes were affected. One case who received intravenous amphotericin B and 3 cases who received intravenous voriconazole improved, and these patients were cured after continual treatment with oral voriconazole for 6 or 12 months. The remaining patients died before they received antifungal treatment.P. marneffei causes severe disease and disseminated infections, and it has high mortality rates in HIV-negative infants in endemic areas. P. marneffei susceptibility may be associated with immunodeficiencies or immune disorders. In endemic areas, clinicians should aware of disseminated

Our study goal was to assess through a retrospective observational analysis whether the administration of the oral probiotic, Streptococcus salivarius K12 (SsK12, could reduce the occurrence of GABHS pharyngo-tonsillar infections in children who had a recent history of recurrent episodes of these infections. Twelve primary care pediatricians identified, through their databases, a total of 130 children who had experienced recurrent GABHS pharyngo-tonsillar infections over a period of at least 6–12 months prior to their inclusion in the study. Of these children, 76 then undertook a 90-day program requiring once-a-day dosing with a commercially available (Bactoblis lozenge containing SsK12. No probiotic supplement was given to the remaining 54 (control children. Each subject was monitored for the occurrence of GABHS pharyngo-tonsillitis and also for acute otitis media, bronchitis, sinusitis, and bronchopneumonia for at least 12 months following their entry to the study. Even 9 months after the use of SsK12 had been stopped, the probability of new GABHS infections was significantly lower (P>0.001 when compared to the period before dosing commenced. When compared to the untreated children, those taking SsK12 appear to have had significantly fewer GABHS infections both during the 90-day period of prophylaxis and during the following 9

    Bovine respiratory disease complex (i.e., shipping fever and bacterial bronchopneumonia) is a multifaceted respiratory illness influenced by numerous environmental factors and microorganisms. Bovine respiratory disease (BRD) is just one component of BRD complex. Because BRD is moderately heritable, it may be possible to reduce the incidence of BRD through genetic selection. The objectives of this study were to determine the heritability and associative genetic relationships among immune system traits (i.e., cortisol, total IgG, IgG isotypes, and IL-8) in cattle monitored for BRD incidence. At an average of 83 d after weaning (219 d age and mean = 221.7 kg [SD 4.34]), crossbred steer calves ( = 2,869) were received at a commercial feedlot in southeastern Colorado over a 2-yr period. At receiving, jugular blood samples were collected at 212 (yr 1) and 226 d (yr 2) of age for immune trait analyses. The BRD phenotype was defined as a binomial variable (0 = no and 1 = yes) and compared with immune system traits measured at receiving (prior to illness onset). An animal identified as BRD positive exhibited ≥ 2 clinical signs (i.e., eye or nasal discharge, cough, lethargy, rapid breathing, acute interstitial pneumonia, or acute upper respiratory syndrome and/or a rectal temperature > 39.7°C). Heritability and genetic correlation estimates for categorical variable BRD, cortisol, IgG, IgG1, IgG2, and IL-8 were estimated from a sire model using ASREML. Heritability estimates were low to moderate for BRD (0.17 ± 0.08), cortisol (0.13 ± 0.05), IgG (0.15 ± 0.05), IgG1 (0.11 ± 0.05), IgG2 (0.24 ± 0.06), and IL-8 (0.30 ± 0.06). A moderate negative genetic correlation was determined between BRD and cortisol ( = -0.19 ± 0.32). Moderate positive correlations were found between BRD with IgG (0.42 ± 0.28), IgG1 (0.36 ± 0.32), and IL-8 ( = 0.26 ± 0.26). Variation in the BRD phenotype and immune system traits suggested herd health improvement may be achieved through genetic

Patients are at risk of postoperative residual curarization (PORC if nondepolarizing muscle relaxants are used. Clinically inapparent insufficient muscle strength may result in hypoventilation and postoperative bronchopneumonia. We describe a cohort of 117 cases in which sugammadex was used in MG patients undergoing surgery with muscle relaxation with rocuronium.Methods and patients: We anesthetized 117 patients with MG using rocuronium and sugammadex as neuromuscular blockade reversal agent. One hundred five patients underwent surgical thymectomy and 12 underwent cholecystectomy (five laparotomic and seven laparoscopic. We measured time from sugammadex administration to recovery and to extubation, using the TOF-Watch® (series of four consecutive electrical impulses [the train-of-four] >0.9. We tracked peripheral capillary oxygen saturation (SpO2 <95%, elevation of partial pressure of carbon dioxide (pCO2 >10% above baseline, number of reintubations within the first 48 hours, and number of pneumonias within 120 hours, postoperatively. Results were processed as average, minimum, and maximum values.Results: The period needed to reach train-of-four of 0.9 following sugammadex administration was on average 117 seconds (minimum of 105 seconds/maximum of 127 seconds and differed within deviation <10%. The time to extubation following sugammadex administration was on average 276 seconds (minimum of 251 seconds/maximum of 305 seconds and differed minimally among patients as well.

    Full Text Available Swine influenza (SI is caused by the type A swine influenza virus (SIV. It is a highly contagious disease with a rapid course and recovery. The major clinical signs and symptoms are cough, fever, anorexia and poor performance. The disease has been associated with other co-infections in many countries, but not in Brazil, where, however, the first outbreak has been reported in 2011. The main aim of this study was to characterize the histological features in association with the immunohistochemical (IHC results for influenza A (IA, porcine circovirus type 2 (PCV2 and porcine reproductive and respiratory syndrome virus (PRRSV in lung samples from 60 pigs submitted to Setor de Patologia Veterinária at the Universidade Federal do Rio Grande do Sul (SPV-UFRGS, Brazil, during 2009-2010. All of these lung samples had changes characterized by interstitial pneumonia with necrotizing bronchiolitis, never observed previously in the evaluation of swine lungs in our laboratory routine. Pigs in this study had showed clinical signs of a respiratory infection. Swine samples originated from Rio Grande do Sul 31 (52%, Santa Catarina 14 (23%, Paraná 11 (18%, and Mato Grosso do Sul 4 (7%. Positive anti-IA IHC labelling was observed in 45% of the cases, which were associated with necrotizing bronchiolitis, atelectasis, purulent bronchopneumonia and hyperemia. Moreover, type II pneumocyte hyperplasia, alveolar and bronchiolar polyp-like structures, bronchus-associated lymphoid tissue (BALT hyperplasia and pleuritis were the significant features in negative anti-IA IHC, which were also associated with chronic lesions. There were only two cases with positive anti-PCV2 IHC and none to PRRSV. Therefore, SIV was the predominant infectious agent in the lung samples studied. The viral antigen is often absent due to the rapid progress of SI, which may explain the negative IHC results for IA (55%; therefore, IHC should be performed at the beginning of the disease.

    Full Text Available History Anthrax has been known since ancient times. Besides some references in the Old Testament, there is evidence of plagues in ancient Egypt, as well as descriptions of the disease by the Roman poet Virgil. Etiology Anthrax is caused by Bacillus anthracis, unmovable, aerobic, gram-positive rods. It forms spores, which can survive for years in the environment. Pathogenesis Capsular polypeptide and anthrax toxin are the principal virulence factors of Bacillus anthracis. Anthrax toxin consists of three proteins called protective antigen, edema factor, and lethal factor. It is thought that the inflammatory mediator - lethal factor is stored within the macrophage during the early stage of infection. It is rapidly released in large amounts into the blood stream and once the threshold for lysis is reached, it may be the cause of sudden death. Epidemiology Grass-eating animals are usually infected by the bacilli from grass and ground. The disease is transmitted to people by contact with the sick animals or their products, such as wool skin, meat etc. Clinical features Two clinical forms exist: outer cutaneous and inner, including inhalation and gastrointestinal anthrax. While cutaneous anthrax is easily cured, the inner forms have high mortality rates. Diagnosis and differential diagnosis The diagnosis is easily established in cutaneous cases, characterized by black eschar. Severe intoxication and collapse during the course of bronchopneumonia or hemorrhagic enteritis should arise suspicion of anthrax. Therapy Hospitalization of patients is mandatory. Bacillus anthracis is susceptible to a number of antibiotics, including penicillin, erythromycin tetracyclines, cephalosporins etc. Prevention General veterinary prevention including vaccination of livestock and control of products is very important. The vaccine consists of anthrax bacillus that is attenuated. The endangered population, such as animal workers and military personnel should be vaccinated

RESULTS: There were 118 deaths in 2006 (mean age: 74.5 ± 15.2 years - 64 women (mean age: 78.4 ± 14.4 years old and 54 men (mean age: 69.8 ± 15.0 years old. Causes of death were sepsis (41 deaths, septic shock (25, bronchopneumonia (16, sudden death (11, multiple-organ failure (9 and other causes (16 deaths. The main underlying diseases were infections (63 deaths - bronchopneumonia (34, sepsis (12, urinary tract infection (7 infected pressure ulcers (7, osteomyelitis (2 and bile duct infection (1; immobility syndrome (42 deaths. The proportion of women older than 75 years showed statistical significance concerning the number of deaths. The sample did not show statistical significance regarding seasonality, causes of death or underlying disease(s when comparing infectious and noninfectious causes of death vs. men and women, aged older or younger than 75 years. CONCLUSION: Deaths in nursing homes were basically caused by a combination of immobility and infections that developed into sepsis.

In both methods the reinstitution of the drug therapy was progressive. The respirator weanned of progressively and the patients were kept under observation for adequate ventilation. The doses were variable but subsequent doses of antimyasthenic medications were determined by clinical findings and response to the tensilon or prostigmine tests. The doses were increased or decreased accordingly in each individual case, rapid changes of drug doses to perfect adjustment being undesirable in this transition period. Partial or temporary remission occurred in some patients. Others were able to sustain satisfactory ventilation for a long period or definitively. Most of the crisis improved and most of the patients benefited from the therapeutic method of the neuromuscular junction rest. There was a remarkable reduction in the mortality rate from the crisis. One patient had a thymoma which was malignant; in spite of this the evolution of this case has been good after the treatment. Those patients who had immediate good response to the treatment of the crisis had a favorable fellow up, even a complete remission. Respiratory infections were very common in spite of all cares. Culture of tracheal secretions and wound exsudates were made. Bactericidal and broad-spectrum antibiotics were used, depending of the laboratory report cf patient's sensitivity. Physiotherapy besides other prophylactic measures was used against bronchopneumonia. Atelectasis was a common complication in the crisis and all efforts to prevent it were made, including daily clinical examination of pulmonary conditions, Vt,, blood pressure and bed side chest films. The routine use of atropine sulfate promoved inspissation of bronchial secretions, plugging of the bronchi, and attendant atelectasis

    patients with acute respiratory failure (ARF and determine whether underlying diseases and certain associated risk factors increase the incidence of these histopathological patterns. METHODS: Final autopsy reports were reviewed, and 3030 autopsies of patients > 1 year of age with an underlying disease and associated risk factors were selected. All had developed diffuse infiltrates and died of ARF-related pulmonary alterations. RESULTS: The principal pulmonary histopathological alterations resulting in immediate death were diffuse alveolar damage (DAD, pulmonary edema, lymphocytic interstitial pneumonia (LIP and alveolar hemorrhage. The principal underlying diseases were AIDS, bronchopneumonia, sepsis, liver cirrhosis, pulmonary thromboembolism, acute myocardial infarction (AMI, cerebrovascular accident, tuberculosis, cancer, chronic kidney failure and leukemia. The principal associated risk factors were as follows: age > 50 years; arterial hypertension; congestive heart failure; chronic obstructive pulmonary disease; and diabetes mellitus. These risk factors and AIDS correlated with a high risk of developing LIP; these same risk factors, if concomitant with sepsis or liver cirrhosis, correlated with a risk of developing DAD; thromboembolism and these risk factors correlated with a risk of developing alveolar hemorrhage; these risk factors and AMI correlated with a risk of developing pulmonary edema. CONCLUSION: Pulmonary findings in patients who died of ARF presented four histopathological patterns: DAD, pulmonary edema, LIP and alveolar hemorrhage. Underlying diseases and certain associated risk factors correlated positively with specific histopathological findings on autopsy.

    Full Text Available Introduction. Multiple myeloma (MM is characterized by the presence of neoplastic proliferating plasma cells. The tumor is generally restricted to the bone marrow. The most common complications include renal insufficiency, hypercalcemia, anemia and reccurent infections. The spectrum of MM neurological complications is diverse, however, involvement of MM in the cerebrospinal fluid (CSF and leptomeningeal infiltration are rare considered. In about 1% of the cases, the disease affects the central nervous system (CNS and presents itself in the form of localized intraparenchymal lesions, solitary cerebral plasmocytoma or CNS myelomatosis (LMM. Case report. We presented the clinical course of a 55-year-old man with MM and LMM proven by malignant plasma cells in the CSF, hospitalized with the pain in the thoracic spine. His medical history was uneventful. There had been no evidence of mental or neurological impairment prior to the seizures. Physical examination showed no abnormalities. After a complete staging, the diagnosis of MM type biclonal gammopathia IgG lambda and free lambda light chains in the stage III was confirmed. The treatment started with systemic chemotherapy (with vincristine, doxorubicin plus high-dose dexamethasone - VAD protocol, radiotherapy and bisphosphonate. The patient developed weakness, nausea, febrility, dispnea, bilateral bronchopneumonia, acute renal insufficiency, confusions, headaches and soon thereafter sensomotor aphasias and right hemiparesis. The patient was treated with the adequate therapy including one hemodyalisis. His neurological status was deteriorated, so Multislice Computed Tomography (MSCT of the head was performed and the findings were normal. Analysis of CSF showed pleocytosis, 26 elements/ mL and increased concentrations of proteins. Cytological analysis revealed an increased number of plasma cells (29%. Electrophoretic analysis of proteins disclosed the existance of monoclonal components in the serum

    Full Text Available We report and discuss the case of a 55-year old man who presented a history of stroke as well as chronic obstructive pulmonary disease. When admitted into the emergency room, he was diagnosed with a vertebro-basilar syndrome. A brain MRI showed a hyperintense area in the lower right brainstem laterally within the medulla, which corresponds to the area of the pathways descending from the autonomic breathing control center. During hospitalization, the patient had several episodes of prolonged apnea, mainly when asleep, having often to be "reminded" to breath. A tracheostomy was then performed with the patient under mechanical ventilation. Treatment with medroxyprogesterone, fluoxetine and acetazolamide was also started. He was discharged after 64 days breathing environmental air with no apparent episodes of apnea. He returned to the emergency room in the following day with a clinical picture of aspiration bronchopneumonia, followed by septic shock and death. CONCLUSION: the Ondine's curse is one of the posterior stroke's presentation characterized by loss of automatic breathing and for the unpredictability of clinical evolution and prognosis. Such a syndrome has rarely been reported in adults and the diagnostic criteria are not consensual in the reviewed literature. Thus any dignostic confirmation should be flexible. There are many therapeutic symptomatic options in such cases, ranging from pharmacologic approach, use of bilevel positive airway pressure and implantation of diaphragmatic pacemaker.Relatamos e discutimos o caso de um paciente de 55 anos de idade que apresentara história de acidente vascular cerebral e doença broncopulmonar obstrutiva crônica.

    battery of other autoimmune encephalitis markers showed negative. A complex program of treatment was applied, including antibiotics, beginning with ceftazidime and ciprofloxacin – for suspected aspiration bronchopneumonia – and thereafter with ceftriaxone. A gradual improvement was noticed and the treatment continued at the Infectious Disease Clinic. Finally, the patient was discharged with a doxycycline, antidepressant, and anxiolytic maintenance treatment. On his first and second control (days 44 and 122 from the disease onset, the patient was stable with no major complaints, Borrelia seropositivity was confirmed both for IgM and IgG while the cerebrospinal fluid also showed reactivity for IgG on immunoblot. On the basis of the putative occupational risk, acute psychotic episode, and the success of antibiotic therapy, we registered this case as a late neuroborreliosis with atypical appearance.Keywords: Borrelia burgdorferi, neuroborreliosis, neuropsychiatric symptoms, encephalitis, anti-NMDAR

  3. Comparison of immunocapture and RT-PCR techniques for the detection of peste-des-petits-ruminants virus (PPRV) in eye and nose swabs from infected animals

    International Nuclear Information System (INIS)

    Full text: Peste des Petits Ruminants (PPR) is a highly contagious disease of domestic and wild small ruminants. It constitutes a major constraint on production in areas where it is endemic. Classically, it is characterised by fever, nasal and ocular discharges, diarrhoea, respiratory distress, mucosal erosive lesions and death in 40-80% of acute cases. All these clinical signs, apart from the respiratory symptoms, are very similar to those of rinderpest (RP). The causal agents of both diseases are viruses which belong to the Morbillivirus genus. Described for the first time in 1942 in Cote d'Ivoire, PPR was considered for a long time as a disease of West African countries. The current knowledge on its epidemiology shows that this is no longer true, nor it is a solely African disease since it is widespread in countries lying between the Sahara and the Equator, in the Middle East and in South-West Asia. These data indicate that PPR existed undetected in most of the known endemic areas for a long time. It was overlooked because of the similarity of clinical signs to rinderpest as indicated above and also to pasteurellosis for the bronchopneumonia. The current knowledge of the disease has grown up quickly once specific diagnostic tests became available in the 1990's: serological diagnosis in the competitive format or for antigen detection by immunocapture cDNA probe and the amplification (RT-PCR) technique for the nucleic acid detection. While the immunocapture (ICE) can detect virus up to 100.6 TCID50 of virus in 50μl of sample, the limit of detection of the RT-PCR is estimated to 0.001 TCD50/ml. During a study to analyse the pathogenicity of some PPRV isolates, we have compared the efficiency of the ICE test, antibody-based antigen detection, and RT-PCR, with the RT-PCR, nucleic acid-based detection technique, to detect the shedding of the virus by the infected animals. For the study, Sahelian goats were inoculated IM with PPRV Guinea (isolate from Guinea Conakry

    were: adenocarcinoma - 20, lipoma - 1, adenomatous polyp - 1, carcinoid - 1, ileocecal Crohn - 1, villous adenoma - 1 and mucocele - 1. Twenty-five patients didn't have complications. A 90 years old woman with an occluded and disseminated sigmoid cancer died from bronchopneumonia in spite of normal intestinal function. Bowel function was restored very early with passage of flatus during the second and third days and stools during the third and fourth days. Tumors 8 cm length or smaller could be handled by small incisions, larger or fixed tumors could not be treated by minilaparotomies. CONCLUSION: Minilaparotomies approach to treat colon diseases seems to be an alternative procedure to conventional or laparoscopic surgery in selected cases. The oncologycal principles and resection for colon cancer are the same as obtained with conventional laparotomies. Recovery was uneventful and without significant pain. It represents a suitable technique with a superior cosmetic effect.

    Full Text Available Rhodococcus equi is a facultative intracellular pathogen associated with bronchopneumonia, mesenteric lymphadenitis and enterocolitis in foals. Although R. equi is likely to be found in every horse-breeding farm, the clinical disease is unrecognized in most of them. Capsule components, equi factor, micolic acid and some products encoded by the large 85-90Kb plasmid were described as virulence factors. However, the pathogenesis of R. equi infections and the sensibility of foals are not completely understood. The aim of this study was evaluate the virulence of R. equi isolated from human, horses and environment for mices. Nine strains carrying the 85-90Kb plasmid isolated from foal clinical specimens, one from immunodeficient human patient and six plasmidless strains (four isolated from feces, one from pasture and one from immunodeficient human patient were inoculated in cyclophosphamide immunossuppressed mice. The pathological changes and viability of R. equi cells in the liver of mice was verified after the 3rd, 6th an 10th day after inoculation for horse and environmental isolates and for R. equi isolates from human patients on the 1st, 3rd and 6th day. During the necropsy procedures, infiltrate of macrophages and pyogranulomatous lesions were detected after the sixth pos-inoculation day in the liver and spleen. In horse isolates, only plasmid positive strains were virulent, but in human isolates both strains (plasmid positive e plasmid negative were virulent. Both groups of the immunossupressed mice inoculated with R. equi isolated from environment showed pathological changes. All R. equi strains were unable to kill non imunossuppressed mice.Rhodococ-cus equi é um patógeno intracelular facultativo associado com broncopneumonia, linfadenite mesentérica e enterocolite em potros.

    Full Text Available Introduction: mortality is one of the trustable and necessary indicator for the analysis of the sanitary situation of a community, and a data source that satisfies an ample cover that allows to define strategies in health actions upon a given population. Objective: to describe aspects related with hidden mortality by cerebrovascular diseases in Intermediate Care Unit. Method: Descriptive and retrospective study of a series of cases carried out during the period 2002-2004 in the hospital ¨Dr. Gustavo Aldereguía Lima¨ of Cienfuegos. All monthly reports of the cerebrovascular diseases attention group were analysed, these being gathered from digitalized data bases from the Hospital Statistics Department (n=3477. An enquiry was applied to obtain information as: year and month of hospitalisation; egress state; decease place if in case; stay; and type of cerebrovascular disease. The deceased necropsy protocols were analysed. Results: The hidden mortality was of 0.05; the main causal entity was the cerebral infarction (71,87%, the behaviour was similar in the five years, the average stay of deceased patients in Intermediate Care Unity was of 4.2 days, and outside this Unity: 8.7 days. It was proved the reduced inn hospital hidden mortality caused by cerebrovascular diseases with lethality definition by these entities during the first days in progressive care. A reduced percent of patients died in other units where an average stay doubles that of the Intermediate Care Unit, and as the main cause: the polymorbility associated to bronchopneumonia.Fundamento:La mortalidad es uno de los indicadores confiables y necesarios para el análisis del estado sanitario de una comunidad y fuente de datos para satisfacer una amplia cobertura que permite definir estrategias en las acciones de salud sobre una población.

Histologically there was a severe acute tubular nephrosis, dispersed foci of coagulative necrosis in the liver, areas of coagulative necrosis in the myocardium and acute incipient interstitial pneumonia as well as secondary bronchopneumonia. Myocardial coagulative necrosis observed in seven sheep was attributed to hyperkalemia secondary to renal insufficiency. No references to spontaneous A. spinosus poisoning in sheep was found in the literature. Attempt to reproduce the poisoning by administration of the plant to sheep was insuccessful, probably because A. spinosus used was not from fertilized areas.

Detectaram-se dois tipos de casos bem definidos: os óbitos ocorridos predominantemente no período neonatal, e cujo processo mórbido envolve quase que exclusivamente as afecções pertencentes ao Capítulo das Perinatais da Classificação Internacional de Doenças; e os óbitos ocorridos principalmente no período pós-neonatal, em cujo processo mórbido aparecem mencionadas significativamente as infecções intestinais, a septicemia, a desnutrição, a desidratação e a broncopneumonia. O estudo da associação entre as principais causas de morte mostrou, por um lado, a imaturidade e a prematuridade fortemente relacionadas com as afecções respiratórias do recém-nascido e com as infecções específicas do período perinatal; e por outro lado, um complexo inter-relacionamento entre as outras cinco causas mencionadas.An analysis of child mortality by causes was made on the basis of classification by multiple causes of death. For this archives containing records of child deaths in the State of S.Paulo (Brazil for 1983 were used. The underlying cause and the associated causes, according to various clustering types, were, among other variables, retrieved from each record. Two types of cases with clearly determined characteristics were detected: those occurring predominantly during the neonatal period with the morbid process involving almost exclusively diseases in the Perinatal chapter (Chapter XV of the International Classification of Diseases, 9th Revision, and those occurring after the neonatal period with their morbid process showing a significant presence of intestinal infections, septicemia, malnutrition, dehydration and bronchopneumonia.

The most important post-mortem findings were enlarged lymphnodes, non-collapsed lungs, with consolidated areas mainly in the cranial lobes. Histological lesions consisted mainly of lymphohistiocytic infiltration with multinucleate giant cells in lymph nodes, spleen, Peyer's patches, kidney, lung and liver, depletion or lymphoid hyperplasia, as well as lymphohistiocytic interstitial pneumonia and areas of secondary bronchopneumonia. The diagnosis was established through observations of the symptoms and typical lesions, and was confirmed by immunohistochemical examination and PCR. The objective of this study was to characterize the epidemiological, clinical and pathological aspects of the outbreak of PMWS, because of the severe direct or indirect economical losses caused by the disease to the world pig industry.

This infection has been associated with bronchopneumonia, meningitis, arthritis, pericarditis, myocarditis, endocarditis, fibrinous polyserositis, septicaemia, rhinitis, and abortion. Streptococcus suis has also been described as a pathogen for ruminants and humans. In Brazil there are several clinical evidences about the existence of S. suis disease in pigs affecting more than 50% of farms in States of São Paulo, Minas Gerais and Paraná. In the present research 51 strains of S. suis isolated from piggeries of the States of São Paulo, Minas Gerais and Paraná were collected from different pathologies such as septicaemia, meningitis, arthritis and pneumonia and been recovered either in pure culture or as the predominant organism from porcine tissues. Culture of specimens was carried out on 5% bovine blood agar plates incubated at 37°C for 24 hr. For the biochemical identification the a-hemolytic colonies of all capsulated isolates were submitted to various conventional tests, such as hydrolysis of arginine, Voges-Proskauer Test, and production of acid from various carbohydrates (inulin, salicin, trehalose, lactose, sucrose, sorbitol, mannitol and glycerol.

All patients fulfilled the Bohan and Peter criteria (1975 and presented anti-Jo-1, articular, muscle and lung involvement. Eighteen patients with anti-Jo-1 ASS were analyzed. RESULTS: The mean age at disease onset was 39.9 ± 15.7 years and average disease duration was 9.7 ± 7.0 years. All subjects were white, and 94.4% were female. Constitutional symptoms occurred in 50 % of cases. There was cutaneous and gastrointestinal tract involvement in 66.6% and 55.6% of cases, respectively. No cases manifested neurologic or cardiac involvement. Half of the patients showed incipient pneumopathy, ground-glass opacities and basal pulmonary fibrosis. There was one case of tuberculosis, three of herpes zoster and one of non-Hodgkin lymphoma. One death occurred due to sepsis shock (hospital bronchopneumonia. All patients received prednisone (1mg/kg/day and 12 (66.7% participants received methyl prednisolone pulse therapy (1g/day, 3 days. Various immunosuppressants were used as corticosteroid tapers, depending on tolerance, side effects and/or refractoriness. Although disease relapse (clinical and/or laboratory occurred in 87.5% of cases, 12 out of 16 patients (75% were in disease remission at study endpoint. CONCLUSION: In the present study, almost all patients were white females and the disease relapse rate was high.

    ão.OBJECTIVE: The aortic valve replacement is a routine procedure, and involves replacement of the native valve/prosthesis. In most of the patients who undergo such procedure the risk is acceptable, but in some cases, such risk can justify contraindication. The minimally invasive transcatheter aortic valve implantation without cardiopulmonary bypass (CPB has been shown to be viable, with lower morbidity and mortality. The aim of this study was to develop a catheter-mounted aortic bioprosthesis for implantation without CPB. METHODS: After developing in animals, three patients with high EuroSCORE underwent implantation. Case 1: patients with bioprosthesis dysfunction; Case 2: severe aortic stenosis; Case 3: dysfunction of aortic bioprosthesis. After minithoracotomy and under echocardiographic and fluoroscopic control, a balloon catheter was placed on aortic position and inflated. After, a second balloon with valved endoprosthesis was positioned and released under high ventricular rate. Echocardiographic and angiographic controls were performed and the patients were referred to ICU. RESULTS: In the first case, implantation without CPB was possible with appropriate results. The patient evolved with improvement of ventricular function. After, this patient developed bronchopneumonia, tracheoesophageal fistula and died due to mediastinitis. Autopsy confirmed proper valve positioning and leaflets preservation. The second case showed the device migration after inflation of the balloon, with the need for urgent median sternotomy, CPB and conventional valve replacement. This patient evolved well and was discharged from the ICU on the 14th postoperative day without complications. This patient developed respiratory infection, septic shock and died on the 60th postoperative day. The patient from the third case underwent successful implantation. CONCLUSION: The off-pump transapical implantation of catheter-mounted bioprosthesis was shown to be a feasible procedure. Technical details and learning

    describe the findings according with the utilized diagnostic methods. Materials and methods: This is a prospective, descriptive and analytic study of 70 patients (3 to 13 years referred to the Cardiology Clinic of the Hospital Nacional de Niños, during a one year period. Every patient had a clinical history, a physical exam, a chest x-ray and ECG and an echocardiogram taken. Results: Only 62 patients completed all their evaluating tests, 3 4 (54.5% boys and 28 (45.2% girls. The mean age was 8.5 years and the median was 9 years. In 21% of the cases the chest x-ray was abnormal (6 showed bronchopneumonia, 2 air trapping, 2 pulmonary artery enlargement, 2 prominent hila and 2 cardiomegaly. The ECG was normal in 97%, the Echocardiogram was abnormal in 4 (1 showed and ASD, 1 a patent ductus arteriosus, 1 a dysplastic pulmonic valve and 1 a pericardial effusion. Stress tests and Holters were normal. Only 4.8% of the patients had heart disease. Conclusion: Consultation for chest pain in the pediatric age is frequent. History and physical examination are very important for the diagnosis and handling of these children.

    alta de la UTI. CONCLUSIONES: La droga escogida para el tratamiento del síndrome de abstinencia alcohólico es el benzodiazepínico. No obstante, en el presente relato, solamente el uso coadyuvante de clonidina consiguió proporcionar tratamiento adecuado al paciente.BACKGROUND AND OBJECTIVES: Sedation of patients with past history of alcohol and drug abuse in Intensive Care Units (ICU is a challenge due to the high incidence of sedative drugs tolerance and withdrawal syndromes. This report aimed at describing a case of a young patient admitted to the ICU who developed alcohol withdrawal syndrome and tolerance to sedatives, resolved only after clonidine administration. CASE REPORT: Male patient, 18 years old, alcohol, tobacco, cocaine and marijuana abuser, victim of firearm accident, who was admitted to the ICU in the first post-enterectomy day, after gastric content aspiration during tracheal re-intubation. Clinical evolution was: vasoactive drugs up to the 4th day; bilateral bronchopneumonia with pleural effusion and need for artificial ventilation up to the 15th day. Initial sedation scheme was the association of midazolam and fentanyl. As from the 4th day, patient presented with several psychomotor agitation episodes, even after the association of lorazepam in the 6th day. In the 9th day, patient received the largest doses but remained agitated. Dexmedetomidine was associated, which has decreased other drug doses in 35% and has improved agitation. In the 12th day, midazolam and dexmedetomidine were replaced by propofol infusion with worsening of agitation. In the 13th day, clonidine was associated to the sedation scheme with total resolution of agitation. Propofol was withdrawn in the 14th day, fentanyl was maintained and midazolam infusion was restarted, with doses 75% and 65% lower as compared to peak doses of such drugs. Patient was extubated in the 15th day and was discharged from ICU. CONCLUSIONS: Benzodiazepines should remain the drugs of choice for the

    described. RESULTS: Pneumonia and bronchopneumonia (51%, asthma (18% and acute and chronical diseases from upper airways (10% accounted for most of the admissions. Children up to five years are most frequently hospitalized, regardless of the specific cause. Among adolescents, the main causes of hospitalization were respiratory diseases that affects mainly the interstitial lung (0.1% and the necrotic and suppurative diseases of lower airways (0.2%. From the age of six to ten years, admissions for acute and chronic diseases from upper airways (10% were predominant. The peak of morbidity occurs in early autumn. There was a trend towards increasing hospital admissions for respiratory illnesses during the analyzed period. CONCLUSIONS: The distribution of hospital admissions for respiratory diseases in children and adolescents is dependent on age and season. The younger the age the greater the number of hospital admissions.
